Bicycle brakes are as essential as they are for other vehicles. Safety depends on the presence and operation of the brakes on a bicycle. All bicycles are equipped with brakes, except for track bikes and those that brake due to deceleration of the pedals.
At the moment, there are many types of brakes that are radically different in design and principle of operation. Bicycle brakes are disc, rim, drum, roller and stirrup. Some are not used at all, and some are rare. Brakes differ in braking power, maintainability and durability. If you are a bike enthusiast and prefer to repair your bike yourself, then you just need to know what kind of brakes a bike has and the device of bicycle brakes. In this article, we will look at all the existing types of bicycle brake systems in order of least popularity.
Drum. foot brake for a bicycle
The foot brake of a bicycle is familiar to everyone and this type of brake was very common on Soviet bicycles. But even now, such a drum brake is successfully used on all types of single-speed bicycles. The drum foot brake is located in the rear hub, an example of which is the most popular torpedo hub. The body of such a sleeve is a drum, and the pads are located inside. When the brake is applied, the pads are pressed against the body and provide smooth braking. For more information on how the rear foot brake works, see our article on rear hubs for bicycles. Drum brakes are divided into two types according to the type of drive:
- Hand-operated. the brake is actuated by a cable. Now this type of drive can be found very rarely.
- Foot-operated. very convenient and does not require unnecessary parts. Braking is carried out by turning the pedals in the opposite direction.
Rear hub with drum foot brake
Drum brakes have significant advantages and many disadvantages.
- Brakes powerful enough to slow down smoothly.
- Due to their design, drum brakes are not subject to contamination, which allows them to be used for a long time without maintenance.
- Drum brakes have no effect on rim wear. In addition, the eights on the wheel do not affect the operation of such a brake in any way.
- Drum brakes are only suitable for single speed bikes and high speed bikes with planetary shift hubs. They are not compatible with other types of bicycles. This disadvantage is the main one, due to which such brakes are not widely used.
- With prolonged braking, they can overheat.
- The drum foot brake is most effective when the cranks are parallel to the road. Accordingly, if the connecting rods are vertically, then it is almost impossible to brake. this is called the dead zone of the brakes.
- When braking, there is a significant load on the hub and wheel spokes.
- If the chain falls off during movement, then the bike is without brakes, which is very dangerous. This problem can be solved by installing additional front rim brakes. Drum brakes can only be fitted to drive wheels.
- It is very difficult to maneuver and still work with the brake.
Bicycle jog and roller brakes
Rapid brakes in their principle of action are somewhat reminiscent of the brakes of railway cars, the brake shoe comes into contact with the wheel protector, the part that forms the contact patch with the road. It makes no sense to talk about the pros and cons of such a braking system, since they have not been produced for a long time. You can only meet steep brakes on very old Soviet bicycles manufactured before the 1960s.
Eager bicycle brakes
Roller brakes are similar in principle to drum brakes (discussed below), but differ in that they can be installed on high-speed bicycles. High expectations were placed on roller brakes and it was believed that in the future they would replace all existing types. But in the process of operation, it became clear that such a brake system has significant drawbacks and a complex design.
Roller bike brakes
- weight than all other braking systems.
- Complex design and high price.
- Does not fit all suspension forks.
- When the brake is depressed, the wheel can spin backwards.
- They are not popular in Russia, so it is difficult to find them on sale.
- Wheel geometry does not affect brake performance. You can use the brakes even with a figure eight on the wheel.
- Complete protection from dirt, dust and water.
- Almost no adjustment is required, these brakes last for years and do not require maintenance.
- One of the most powerful brakes without affecting rim wear.
Such brakes are called rim brakes because braking is carried out due to the friction of the brake pads on a special track of the bicycle wheel rim. Rim brakes are the most popular type of brakes today. They provide good braking power and good maintainability. The design of all rim brakes is the same, but the principle of operation may be different. Rim braking systems consist of a handle, cable, levers and brake pads. These braking systems are ideal for beginners as they are easy to install, adjust and even repair in the field.
There are four types of rim braking systems. caliper, cantilever, hydraulic and V-brake. Let’s consider each type in more detail:
- V. brake. vector rim brakes. The levers of such brakes are attached in a V-shape, and a cable comes from the side to one of the levers and connects both levers. This system provides the best braking power of any rim brake. The vector brake levers are attached to special mounts on the frame (brake. Bosses), if they are not there, then you can install removable adapter mounts. V. brake brakes are by far the most popular and even overtake disc brakes in popularity.
V. brake. vector brakes
- Cantilever brakes are the forerunners of vector brakes. These braking systems were once the most popular of all types of bicycles. But with the advent of the V. brake, brakes began to decrease their position and are now almost never used. These brakes are a little harder to set up, but if done correctly they are as effective as other rim brakes.
- Tick-borne. the name comes from the shape of the arrangement of the levers, which resemble ticks. Currently used mainly on road bikes. These brakes are lighter in weight, but have only one mount, which makes them less durable.
Caliper U. Brakes
- Hydraulic is a braking system in which the force from the handle is transmitted to the levers using a hydraulic line. The hydraulic fluid can be brake fluid or special oil.
Let’s note the pros and cons of the most popular rim brakes. V. brake.
- Dirt, water, sand and snow trapped between the rim and pad will reduce braking performance and even affect rim wear.
Rim brakes are highly susceptible to dirt
- Affect the geometry of the frame and can move the frame stays apart.
- On bicycles designed for extreme disciplines, there is an accelerated process of wiping the wheel rim.
- Rapid wear of the pads, and therefore their frequent replacement.
- Rim geometry greatly affects brake performance.
- Low stress on the spokes and hubs of the bike.
- Significantly low cost relative to disc brakes.
- Do not heat up during prolonged use.
- Low weight relative to the same disc brakes.
- Very easy installation, setup and repair.
Bicycle disc brakes
The most modern type of brakes borrowed from motorcycles and cars. The disc brake system consists of a handle, cable or hose, rotor, caliper and pads. The rotor is a brake disc that is attached to the hub of the bike and is clamped with pads using a caliper that is attached to the bike frame in the area of the fork dropouts. Compression of the pads occurs by transferring force from the handle to the caliper through a brake hose or cable. The brake fluid or special oil can be used as a fluid in the hydraulic line.

- The rotor and disc brake pads are almost free of contamination as they are in the center of the wheel.
- Disc brake allows for smoother braking.
- The geometry of the rim and figure eights does not affect the performance of such brakes.
- The rim does not wear out, and the disc brake system itself is almost maintenance-free.
Bicycle jog and roller brakes
Stiff brakes are reminiscent of train brakes: the brake shoe is pressed directly against the wheel tread. There is no need to talk a lot about the features of this system, since you will not find such a design on new bicycles for a long time. The speed brake is still used on bicycles in India and China. Fortunately, these models do not enter our market.
Roller brakes emerged as a result of the desire of one large manufacturer of bicycle components to make the perfect brake by removing the disadvantages of drum brakes (we’ll talk about them below). The brake hub was replaced with rollers, and the brake drum was fitted with a radiator for better cooling and removed from the wheel hub. The roller system does not require frequent maintenance and provides effective braking during normal driving. With a leisurely ride, these brakes serve for years without any adjustments. At the same time, in harsh operating conditions, roller brakes have no advantage.
Disadvantages of roller brakes:
- The largest weight of all braking systems.
- The complexity of the design and a considerable price.
- Most suspension forks do not support this type of brake.
- The brake does not block the rotation of the wheel in the opposite direction.
- The exclusive design makes it difficult to find spare parts, and there are no cheap consumables.
Roller brakes advantages:
- The rim geometry does not affect brake performance. Eights and eggs do not reduce braking performance
- Excellent protection against dirt, dust and good water resistance.
- They require a minimum of adjustments and, with proper maintenance, are eternal.
- Almost the most efficient brakes.
Drum brake for bike
Everybody knows the foot brake of a bicycle. this is the most popular brake on bicycles of the Soviet era. Even today it is the most popular single speed bike brake. The drum brake is located in the rear hub, the body of such a hub acts as a drum, and the pads are located inside. When the brake is applied, the pads are pressed against the inner surface of the hub and provide braking.
The brake drive can be manual, cable, or foot, pedaling in the opposite direction. The manual drive is practically not used.
Drum brakes have significant advantages and no less noticeable design disadvantages.
Drum brakes advantages:
- Powerful brakes with stepless deceleration control.
- Virtually sealed, requiring a minimum of maintenance.
- Do not wear out or place special requirements on the wheel rim.
Disadvantages of drum brakes:
- The main disadvantage is incompatibility with rear derailleur gearshift systems. Therefore, they are used on single-speed or bicycles with a planetary hub.
- Poorly cooled and even on small long descents lose efficiency.
- The braking force depends on the position of the pedal cranks in relation to the road. If the connecting rods are perpendicular to the road, the braking force tends to 0.
- Significantly load the hub and wheel spokes.
- If your bike’s chain has fallen off, then you lose the brakes. This is very dangerous and the drum brake must be duplicated with a rim brake.
- It is very difficult to actively pedal and still use the brake.
Like any other high-speed vehicle, a bicycle needs brakes. The safety of the cyclist depends on the quality of the brakes. It should be mentioned that track and some other models do without a mechanical brake system. The pedals are rigidly connected through a chain to the rear wheel hub, and braking is performed by slowing down the rotation of the pedals or by suddenly transferring the cyclist’s weight to one pedal, followed by blocking the drive wheel.
Anyone can understand that blocking has a negative effect on the condition of the tire, and the skidding movement of the wheel complicates the handling of the bicycle. For a sports bike, the absence of a brake is a way to reduce weight and increase the reliability of the structure, but riding such bicycles requires special equipment and will not add comfort to an ordinary person.
In general, the topic of choosing brakes is one of the most confusing and scandalous topics regarding the choice of bicycle components. Brakes differ in braking efficiency, maintainability, and durability. Many people with different experiences and needs are supporters of one design or another.
In the article we will give an idea about the design of braking systems and mentioning the advantages and disadvantages of each, we will start the review with the least common. Even if you do not plan to service the bike yourself, you will need the knowledge to choose the brakes to replace the worn out ones or if the old brakes cease to suit you.
Braking is provided by pressing the brake pads against a special track on the wheel rim. The most popular type of brakes today. Sufficiently effective brakes with excellent maintainability.
They differ in the way the brake pads are brought to the rim, but the principle of operation of different options for rim brakes is the same. Ideal for beginners: easy to set up, easy to adjust and very easy to repair in the field.
There are four types of rim brakes: caliper, cantilever, hydraulic and V-brakes. about each type:
- V. brake. When fully closed, the brake levers form a V. Best performance of any rim brake. The most demanded type and even overtake disc ones in popularity.
- Cantilevers are the prototype of V-brake brakes. Have been popular in the past. difficult to set up, with the advent of V-brake, have lost their relevance.
- Tick-borne. so called because of the levers, which resemble ticks in appearance. Today they are used only on road models due to the smallest mass. Less durable than other types due to only one attachment point to the fork.
- Hydraulic. the force from the brake lever to the brake pads is transmitted by a hydraulic line filled with a special fluid.
The advantages and disadvantages of all types of rim brakes are the same.
Disadvantages of rim brakes:
- Any particles or liquid trapped between the surface of the rim and the brake pads will reduce the braking efficiency, accelerate the wear of the pads, and in severe cases, remove the chips and wipe the rim.
- May bend or spread the bike fork stays.
- Brake pads wear out pretty quickly. Fortunately, they are inexpensive.
- A bent rim greatly reduces brake performance and causes uneven pad wear.
Advantages of rim brakes:
- Light stress on the spokes and rim of the bike.
- Low price compared to disc brakes.
- Allows extended use of the brake, although may overheat the rim.
- Very light when compared to disc brakes.
- Easy maintenance and setup.
Bicycle disc brakes
Disc brakes are the most modern brakes, rapidly replacing all other types. They consist of a brake lever, brake cable or hydraulic line, brake disc (rotor) and brake machine (caliper).
The force from the brake lever is transmitted through a cable or hydraulic line to the brake machine. a caliper attached to the fork near the wheel axle. The caliper transmits force to the brake pads and compresses the rotor mounted on the wheel hub.
The advantages of disc brakes:
- Rotor and pads are high off the road and slightly dirty.
- Disc brake allows precise adjustment of the braking force.
- Wheel rim geometry does not affect braking performance.
- The rim does not wear out, with proper adjustment, the long service life of the mechanism.
Disadvantages of disc brakes:
- Brake pads from different brands are not compatible with each other.
- Overloading the wheel hub and spokes during braking.
- Repair requires qualifications and special tools and is almost impossible in the field.
- weight than rim systems.
- Good disc brakes are expensive. And cheap discs are inferior in efficiency to equal in price or cheaper rims.
- The caliper may interfere with the installation of a rear rack on a bike.
With all the variety of braking systems, the main competition today is between V-brakes and disc brakes. V-brakes occupy the lower price point, as well as the sports segment with stringent bike weight requirements. Although disc brakes are considered the future, rim brakes are still very good for normal non-aggressive driving.

When you really need to adjust your brakes
Now, having studied the situations in which you need to adjust the brakes, let’s get down to business.
How to adjust the brakes on a bike?
Professional cyclists have one funny and very apt saying: It’s important to be able to pick up speed, but the real skill is to stop on time.
How to adjust the brakes on a bike?
Professional cyclists have one funny and very apt saying: It’s important to get up to speed, but the real skill is to stop on time. And yes, we are talking here, of course, about brakes. this is the most important component of any vehicle, without which it is not allowed to drive at all. Correctly tuned brakes are a guarantee of a pleasant ride, precise speed modulation and, of course, your personal safety. Misaligned or damaged brakes are a guarantor of trouble.
That is why it is so important to figure this out on your own. yes, your master will surely cope with any problem, but the need to adjust the brake pads may arise right during the trip. And you better take care of your awareness in this matter in advance.
We bring to your attention a complete instruction on how to adjust (adjust) the brakes on a bicycle. After reading all the points of the article, you will easily cope with any problem of low or medium complexity. complex operations, such as disassembling mechanisms and replacing internal components, are still better carried out under the supervision of a professional master.
There are three types of rim brakes:
WHAT MAKES IT WORK? #13 The Bicycle Coaster Brake tubalcain
In about 80 out of 100 cases, the bike will have vibrake rim brakes. If your bike is not yet 10 years old, then the probability is reduced to almost one hundred percent. this is a vibrake. This type of rim brake is simple and provides maximum braking power. Speaking about setting up rim brakes, we will mean exactly vibrating racks.
Next, you must adhere strictly to the order of actions. we proceed to remove the brake.
- Carefully take the cable jacket and remove it from the holder. This is how the brake is released, which is necessary for further maintenance.
- Unscrew the screw securing the brake levers with holders to the bike frame.
- After unscrewing the screws and taking out the shirts, we remove the brakes themselves from the steering wheel.
- The fourth step is performed only if you are going to work with the pads. you need to unscrew the screws that fix them. In this case, you need to unscrew very carefully, clearly remembering the sequence of all removed washers. With their help, adjustment will be carried out, so they must stand correctly.
If you have released the brakes on your wheels, then most likely you are going to change or update the pads. The latter is done when the bike was in a cold room for a long time or participated in a serious race where it was necessary to slow down a lot. The essence of the update is that the outer layer of rubber is simply removed, because it becomes too hard, and therefore completely unusable.
Replacing the pads is even easier. just remove the old rubber, and put a new one in its place, if necessary, carefully trimming it with a clerical knife. If the block is cartridge, then it simply changes the cartridge.
Having finished replacing the pads, let’s move on to adjusting the tension of the cables. The cables, or rather the degree of their tension, regulate the distance from the shoe to the wheel rim. To adjust this moment, you need to turn a special screw located on the brake lever. This should be done with the brakes already assembled. If such an adjustment does not help, you will have to unscrew the cable retainer and shorten it, much less often a slight lengthening is required. To unscrew the retainer, you will need a hexagon. it’s easy to do, you don’t have to worry about possible difficulties.
Next, you need to adjust the position and angle of the shoe. To do this, you do not need to remove the wheels, otherwise it will not be possible to clearly place the block. When aligning, follow three simple rules.
- In any case, the pads must be in the plane of the rim. Not a single pad should go beyond its boundaries. this will damage the brakes.
- The correct position of the pads is parallel to the rim. This position should be maintained regardless of whether you apply force to the brake levers or not.
- By the rotation vector. This is how the pads are supposed to act on the rims. if they are really parallel, then they will.
After making the adjustments and adjustments, you just need to put all the screws back in place, fix the loose clips, and check the brakes. over, note that it is imperative to check the brakes both at home and in real conditions. after a test drive, you will most likely need an adjustment.
Adjusting disc brakes
First of all, it is worth checking if the rotor is damaged. If there are chips and bursting areas on it, then no adjustment will help. the brakes will still not work correctly. In case of a damaged rotor, it will need to be replaced.
As for the types of disc brakes, they are mechanical and hydraulic. The latter are mainly put on high-end bikes, because they cost a lot. The only difference between setting up disc hydraulics and mechanics is working with brake fluid. Before winter, for example, it will need to be drained a little. This will help increase pad free play.
In disc brakes, it is most often required to adjust the angle of pressing the pads against the rotor. Do not forget that first of all they must be strictly parallel to each other.
So, the brake pads on disc brakes are located in the caliper. this is a special device that is attached to the frame and on the bike fork using an adapter. Follow the steps below to adjust the caliper and pads.
- Take the wheel and secure it in the position that you will use directly for driving.
- Next, you need to see how the caliper works, for this you need to loosen the screws fixing it a little.
- Now you need to push the brake lever to see how the caliper moves and returns to its place. Also don’t forget to check the clearances.
- Then it remains to tighten the machine, and fasten the screws one by one. that’s the whole setting.
Also, when adjusting disc brakes, you may need to adjust the length of the fixing cables. This is done in the same way as with rim brakes. The mount is untwisted, then the cable is released, shortened or lengthened, the mount is screwed back.
Step. determine the type of brakes
The type of brakes fitted to your bike depends primarily on your riding style. Let’s figure it out with clear examples.
- Foot. They are installed on the simplest city models, and on almost all walking bike models, for example, cruisers. Such brakes are very simple in structure, effective and reliable. In addition, and most surprisingly, the foot brakes do not need to be adjusted at all. They have one peculiarity: the longer you use them, the more force you need to apply for effective braking. This, by and large, is the only problem that can arise with such brakes, and it is solved by replacing the internal pads. This should be done by the master, it is not recommended to disassemble the brakes himself. there is a risk of wasting time, and gaining a lot of nerves, after which you still have to contact the master.
- Rim. They are used on walking bikes, city bikes, road bikes, road bikes, mountain bikes and even jumping bikes. They are very simple in design, efficient, reliable, and most importantly, they weigh little. That is, despite insignificant obsolescence, rim brakes continue to be used all over the world. Their only drawback is that with prolonged use, the wheel rim is depleted, which leads to its destruction. Disc brakes look like this: two handlebars on the steering wheel that receive pressure, a system of cables, and two small mechanisms with pads on each wheel. force is imparted to them, after which an effective action takes place, that is, braking.
- Disc brakes. The most progressive of all the varieties that exist today, they are superior to rims in everything, with the exception of two parameters. they weigh more, and require the installation of a special rotor on the drum, which makes it impossible to install, for example, a trunk. In general, disc brakes are the most effective and are used by professional riders to maximize ride control. Therefore, it is disc brakes that are installed on high-level mountain bikes, as well as on bicycles for extreme riding. it is no longer possible to come up with something more effective. Due to braking through the rotor, the wheel rim does not suffer at all, and the very condition of the wheel does not in the least affect the braking. The last disadvantage of disc brakes is that they require powerful spokes from the bike, because the braking force is transmitted from the rotor through the spokes to the wheel.
Within the framework of a specific article, we will talk about rim and disc brakes. these are the most common types, and besides, they really need regular adjustment, which cannot be said about the foot brake. But before that, we’ll figure out how to tell if the brakes on your bike really need tuning.
After adjusting the brakes, you will need a full test drive. If, say, you decide to go straight to work by bike, then you risk ruining your trip, endangering your own safety. Therefore, always after adjusting, you need to take tools with you and ride a bike to determine how the brakes work in real conditions. This is the only way to gain the confidence in your own bike, which will be so useful for you on the long journey.
So, if your bike has a foot brake, you don’t need to adjust it. If it is rim or disk, which is much more likely, then the article describes the tuning process step by step for each of the cases.
In fact, adjusting the brakes is not necessary very often, but it can cost you a pretty penny, especially if you decide to contact a professional bike salon. Therefore, the ability to independently adjust the brakes is not only convenient and useful, but also keeps your budget from unnecessary items of expenditure.
In the conditions of our off-road conditions, the question of purchasing a comfortable, functional and durable bike is relevant. Such units are found among budget models, but it is difficult to make a choice, since the market is full of assorted bicycles. First you need to decide what goals you are pursuing: you want a frantic drive on rocky slopes or you need a reliable mountain bike for driving on urban asphalt and forest terrain.
Today the market presents a wide range of bicycles for every taste, color and wallet. The huge number of proposals is difficult for a layman to understand. To make the right choice of a two-wheeled friend, you should familiarize yourself with the general classification and purpose.
A standard frame made of wood on runners. these are the sleds preserved in the memory of most parents. But manufacturers and technologies do not remain in place, and the rating of the best sleds in 2020 will be a confirmation of this.
Between foot brake and hand brake
Once upon a time, the choice of a bicycle was limited to the correct height parameters, brand and color. Today the assortment is so diverse that it is simply impossible to pick up even a simple urban model without minimal knowledge of the structure of modern bikes. In particular, this applies to the variety of braking systems.
Alternatively, advanced models are equipped with mechanically or hydraulically actuated disc brakes. It is worth noting that the cost of such systems is several times higher, and the device is much more complicated. However, disc brakes are most reliable in extreme conditions. They are not sensitive to the vagaries of the weather or the characteristics of the coating. Their only drawback is the complexity of the repair: if the disk hydraulics fail, they will have to go to the workshop.
Habitual foot brake
If you learned to ride a bike as a child, you are most likely used to using the foot brake. The principle of its operation is extremely simple: in this case, a chain drive serves as a drive and, in order to start braking, you need to turn the pedals in the opposite direction. Such a device works fine on singlespeeds, but is incompatible with traditional manual transmission.
Thus, the foot brake has survived as an attribute of fixed speed urban bicycles. The mechanism itself is located in the rear axle, which offers a number of advantages:
- the tightness of the device guarantees protection from precipitation, road dust and dirt;
- lack of maintenance or frequent repairs;
- overheating of the rim is excluded.
However, in some cases, the foot brake may not be reliable enough. For example, if the chain comes off or breaks when your feet accidentally slide off the pedals, you will not be able to use the foot brake for an emergency stop.
Most manufacturers install hand brakes that can complement the foot brakes or work independently. Over the years, they have built a reputation for being stable and safe. regardless of design. All braking systems on the market are divided into rim and disc, both have supporters and opponents.
When completing city bicycles, V-Brake rim brakes are most often used. They are distinguished by good power, unpretentious maintenance and simple service in the event of a breakdown. However, in rainy weather or on strong off-road conditions, such a system can easily become clogged, which reduces the quality of work.
Which brakes are better?
The optimal solution for a particular bike depends on its purpose. So, for a city bike that will never test its strength in the deaf off-road or on a downhill, V-Brake rim brakes are more than enough. Some models are equipped with foot and rim hand brakes for the convenience and safety of cyclists. Thus, the systems duplicate each other, ensuring maximum safety.
Bicycle foot brake repair
Bicycle foot brake is a device that provides smooth braking of the driving rear wheel. Other names are pedal brake, drum brake. The location of the node in the structure of the bicycle is the rear axle. Used as a primary brake or supplemented with a manual front brake. Scope of application. old bicycles of the USSR period, children’s bicycles, singlespeeds, modern city bicycles with a fixed speed, with one gear or with a planetary type gear derailleur. The device is incompatible with the classic manual transmission system.
Operating principle. For braking, the pedals rotate in the opposite direction, opposite to the working rotation. The drive functions are performed by a chain drive. The rear wheel hub or a portion thereof is a drum. When braking, the inner brake pads assume the position of the spacer and brake drum clamp.
Technical features. The rear foot brake system on freewheel bikes allows for tricky freestyle tricks by rolling backward without forcing the bicycle pedals.
- 1 Frequent bicycle foot brake repairs and scrupulous care are not required.
- 2 Due to the tightness of the structure, protection against dust, dirt, rain is guaranteed.
- 3 When using this type of brake, the rim does not overheat.
- 4 The device has a low cost.
- 5 The mechanism allows you to ride a bicycle with a curved wheel geometry (figure eight).
- 1 Impossibility of emergency braking in the event of a chain break or foot slipping off the pedal.
- 2 The need for some getting used to the effective use of the foot brake.
- 3 Lack of compatibility with external derailleur.
- 4 Additional load on hub and spoke during braking.
- 5 Low braking power.
- 6 Difficulty maneuvering with alternating braking and acceleration.
- 7 Possibility of overheating during long descents from the mountains.
When is it necessary to repair or prevent a bicycle foot brake?
The drum brake is durable and durable. However, the node needs to be checked, debugged, or replaced periodically. To test the functionality of the device, you need to rotate the bicycle pedals in the opposite direction. With a working mechanism, the brake is applied after the reverse stroke of the pedals has made a quarter of a wheel turn. If the brake is applied later, the device does not work correctly. Since the foot brake mechanism is fully housed in the interior of the rear hub, self service is not recommended. Disassembly should be entrusted to a qualified bicycle technician.
Check the brake control lever periodically. Structurally, it is a flat steel handle (on the brakes of the Bendix brand). The lever is connected to the rear axle and is attached to the bicycle frame. When checking, make sure that the mount is fixed. Loss of locking can cause the control arm to rotate with the axle. If the lever is found to be detached, it must be locked towards the nose of the bike.
