How to set up brakes on a bicycle disc stealth

Mechanical type

The adjustment is carried out if there is friction between the disc and the pad. A procedure will also be required in case of deterioration in the work of the part.

The brake lever is squeezed to the limit. Unscrew the locknut of the machine, then turn the regulator out. It may be necessary to loosen the cable. In cases where the brakes are installed crookedly, it is necessary to loosen the adjusting screws. Unscrew the screws securing the braking device. When the caliper becomes movable, squeeze the handle to the limit and lock in the specified position. Center the machine on the disc. Then you need to tighten the screws securing the machine. Repeat the procedure periodically to avoid movement of parts.

After completing the process, lower the handle. To avoid permanent shifts, follow the recommendations given in the operating instructions.

System check before the procedure

Make sure the adapter is securely attached to the bike frame before adjusting. Examine the rotor. Normally, the part is smooth, tightly screwed to the sleeve. Check the element for deformation. To do this, lay it on a flat surface. A loose fit indicates a need for alignment. Wheels must be screwed tight.

If a mechanical braking system is installed, it will be necessary to check the condition of the jackets and cables. Replace loose cables with torn fibers. Cracks or tears on the shirt are also a reason for replacement.

Hydraulic brakes require a hydraulic line check. If leaks or damage are found, it is recommended to replace the element. Should be changed even with minor breakdowns.

Inspect every element of the system. If any is found to be in poor condition, damaged, replace it. Carry out such inspections on a regular basis in order to timely replace worn out parts. If you ignore this procedure, driving becomes dangerous.

Oil and dirt gradually build up on the rotor and brake pads. Please remove them before configuring. It is recommended that you wipe the parts regularly as dirt can cause breakage. The elements should be wiped with sandpaper. Don’t rub aggressively. It is enough to get rid of the thin layer. When the procedure is completed, avoid touching the treated parts with your fingers or greasy compounds.

Determine if the rear wheel is installed correctly. It is normally located at right angles to the surface, does not warp. Place the vehicle on the wheels, slightly loosen the eccentric, push down on the saddle and tighten the eccentric.

How to set up disc brakes on a bicycle?

How to set up disc brakes on a bike is something that many novice riders do not know. Technologically, such parts are more advanced than the V-brake, thanks to which they perform their functions better. However, you should not buy low-quality cheap parts.

Adjusting bike brakes

  • mechanical;
  • hydraulic.

Each option has its own adjustment features. If in doubt about your abilities, contact the service center to specialists.

Hydraulic disc

Adjustment of disc brakes will be required when unpleasant sounds, squeaks, grinding, or when there is strong wheel resistance when driving.

Remove the caliper bolts. After that, squeeze the handle as much as possible to press the pads against the wheel. Consider the position of the valves. Parts must be at the same distance from the rotor. If the gaps are uneven, press down 1 element, then work with the handle 10 times. In this case, the unevenness should disappear. Tighten all screws. When the caliper is locked, lower the handle. In this case, the block should not press against the rim. The clearance to the stationary part is normally about 1 mm.

The adjustment is completed by setting the handle to the required position. To fix the part, a special hexagon is used.

Final check

When the work is finished, check how the brakes work. It is not necessary to go far. it is better to check in front of the house or service center. If the parts function well, the job is done. If problems are found, re-inspect the bike, try troubleshooting.

How to adjust the brakes on a bike

The accuracy of the mechanism depends entirely on the correct setting. Thus, even the most expensive design will function poorly without proper adjustment, and vice versa, with professional maintenance, budget models will work fine. How the rim brakes of a bicycle are adjusted?

Note: Diamond screws can be easily lubricated with grease to facilitate tightening. It can also be disassembled over time. Continue by joining the saddle and seat you found in the included box. The saddle must always be firmly pressed against the saddle.

Classic lock: Tighten on both sides with a 14 mm spanner. Pivot system: the saddle has a hex screw in the middle and ends with “teeth”. The screw passes through the center of the saddle tube. The key seat can only be connected with a swivel seat that ends with an end and thread for the seat anchor bolt.

  • First, the cable tension is adjusted. Due to the settings made for the v-brake, the brake should quickly pick up the signal when the handle is pressed and stop braking when it is released. If there is no bouncing of the pads, then the cable is not tensioned enough. However, there are cases of an overtightened cable, then the handle will be pressed with force, and the braid may crack at all. Tension can be adjusted by turning the bolt on the side of the levers. If the cable fibers are slightly or severely damaged, you should undoubtedly replace them with another set.
  • Next, you need to adjust the clearances. The optimal gap is two to three millimeters from the end of the last to the beginning of the rim. It is forbidden to use the unsuitability of pads on a bike when the surface of one side or the entire part is worn out to a level.
  • The final stage is a practical test of the functioning of the great, that is, under real riding conditions. In almost all cases, the correct installation of the v-brake (vector) brakes is obtained the first time. However, when braking is slightly delayed or the handle does not instantly return to its original position, it is necessary to inspect and adjust the system again.

Always pay attention to the correct seat tilt. It mostly has a slight backward curve. Preferably, the tilt is mounted directly on the bike. Seal the saddle tube lightly with grease before inserting it into the frame. Plus, you prevent unwanted scratches in the saddle post. The maximum extension of the seat support must not exceed the top edge of the warning sign located at the bottom of the seat post.

You also found the pedals in the package. They are always divided into left and right pedals. You can find the markings on the axle on the thread or on the edge. Align the axles with grease before installing the pedal. Practical advice. Always tighten both pedals to tighten the front wheel. Turn the key on the rear wheel to turn it on.

With this note, the brake setting on the bike is completed. From now on, you know how to properly adjust the brakes on a bicycle with your own hands, you will not be scared in the event of a breakdown. If more fine adjustment is required, it can be done while riding with the handlebars. Feel free to start traveling and conquer new horizons!

From the correct operation of the brakes. An important part of the bicycle depends not only on the health of the cyclist, but on his life, and the life of other road users. Therefore, when buying this two-wheeled vehicle, it is important to choose a model with a reliable braking system that will stop the bike almost instantly in an emergency.

brakes, bicycle, disc, stealth

Use a 15mm wrench to tighten the pedals. Pedal studs often cause shaving injuries, which is why we recommend buying. Next comes the front wheel mount. Choose which side you will place the pegs on. Most of the pins are installed on the front leg. Remove the rescue pad from the front wheel axle and place the pin on the 10mm axle. Insert the front wheel into the forks. On the “no tie” side, you can insert the rescue pad into the hole in the fork above the axle.

Place the front wheel in the fork and tighten. In the future, it is important to check that the string is tightened correctly and that the rim is clean. The rigid stance improves overall ride stability. The spinning wheel is a natural wear and tear due to use and is not covered by the warranty.

Types of brakes

Do they use V brake or disc brakes more often than others? Making a choice in favor of v brake brakes or otherwise is not always easy due to the wide variety of braking systems.

  • mechanical, using a jacket with a cable for compression, are subdivided into cantilever and tick-borne;
  • hydraulic, stopping with brake fluid pumped into the hydraulic line.

Rims affect the performance of the brakes, so they should never be damaged, wet or greasy. Most colored rings are “engraved” on their braking surfaces over time and fade. Let’s move on to the front and rear wheel inflation steps. Observe the maximum overvalues ​​on the sides of the housing. It is especially necessary to stick to folding tires!

Another quick step. put in the rear pin. You place it on the same side as your front foot and front foot. A common mistake is to insert a pad between the frame foot and the anchor. Make sure the wheel is at the back before tightening. If the rear wheel is tightened on one side, the rear brake cannot be adjusted correctly.

The choice of one type or another is influenced by the following factors:

  • operating mode, i.e. how and where it is supposed to go;
  • amount you can spend.

The penultimate step and very important is the rear brake design. We recommend the following steps for the brake lever. Gently lift the handlebar brake lever firmly tighten the brake lever lock screw as shown in the left photo Wipe the steel wire in the bucket with oil.

Engage them, then press the brake lip towards the rim, guiding the brake unit all the way and pulling it out. Be careful to bend or turn away from the rim frequently. Repeat the brake pad until you are satisfied. If you tighten the spring, the brake will be difficult, but if you play with it, the brake will “move” very easily. Tighten the hex screw after tightening the spring Repeat the same spring tension on the other jaw. The tension of the second spring should be very similar so that the brake moves symmetrically.

The group of rims includes vibrake, which are much cheaper than disc.

The principle of operation of v brake brakes (if you do not pay attention to some details) is unusually simple: the pads on both sides simultaneously compress the rim due to the force transmitted by the cable from the brake lever, as a result of which the wheel stops.

Tighten again with the socket head cap screw. It is always best to assemble the brake when the bucket and cable are lubricated with oil or grease. Regular oil is thrown through the entire skeleton When adjusting the brake cable, make sure that the stop bolt in the brake lever is fully screwed in, but the lower stop bolt is screwed in half. This allows the brake to be pulled or applied. This is important because the bow often sits with the ends of the bowling alley and you can easily reset the brake. The last step of adjusting the brake. cut off excess wire.

From the nineties until recently, there was no alternative to rim brakes. Most of the designs were equipped with rim brakes for the bike. Then disc brakes appeared, but vibrake brakes have not lost their relevance due to a number of advantages. They are still popular nowadays, which is why they are found on many bicycles. So, which one to give preference to. disc or rim brakes?

We recommend leaving at least 1.5 cm of overlap at the end of the cable. All the workflows you followed involved folding the wheel out of the box. This means that some parts have already been installed on the bike from production. However, for safety reasons, it is important to check that all parts on the bike are properly tightened. Therefore, we recommend that you perform a preliminary check to detect any inaccuracies.

Often, immediately after the first two or three trips, the parts become so-called. Take advantage of our discussion forum, where we will be happy to inform you not only us, but above all others. Most of our bikes have mostly skipped winter, but now is the time to change! Before jumping into the first jump, it is good to check the technical condition of your bike.

disadvantages

  • constructive variety even in the same model range, which excludes interchangeability;
  • difficulty in finding spare parts and maintenance;
  • the complexity of repairs in the field (you need special tools, cleanliness, concentration;
  • difficulty during transportation (it is easy to bend the disk on a removed wheel), but it is quite difficult to straighten it;
  • the danger of oil getting on the disc during lubrication, leading to brake failure and requiring replacement of the pads, which is quite expensive;
  • toxic brake fluid used in many DOT models). With careless maintenance, hitting the frame leads to damage to its coating;
  • the risk of boiling on long descents of brake fluid, which leads to loss of control of the bike;
  • problems with installing the trunk;
  • more weight than v-brake;
  • high cost (2-4 times in comparison with analogues).

From the foregoing, the conclusion suggests itself: in the segment of bicycles with a price above 20 thousand rubles v brake, the brakes have clearly lost ground. This is due to the fact that more and more damping frames and forks are produced with holes designed for disc brake calipers installed on expensive bicycle models.

But, on vehicles of the segment up to 15 thousand rubles. those. budget models, they are not installed, so this niche still belongs to v-brakes.

Whether to buy a bike with mechanical or hydraulic disc brakes depends on how the bike is going to be used. Preference is given to disc brakes if their benefits are really needed. In other cases, choose a reliable, lightweight, simple and durable V-brak.

Benefits

Their high popularity is due to their low weight, normal braking force, lightness, cheapness, and ease of maintenance. It is easy to replace the cable and pads, for example, in any conditions, having a hexagon.

Lubrication of the cable rope. For optimal use of the rope cable, it is good to use a special oil for its surface. Choosing a cable is a good choice. The strong fiber combined with quality balls works under standard conditions in harsh conditions, both rain and frost. Even if we all have to hide, the brakes need to be functional.

brakes, bicycle, disc, stealth

In the case of a torpedo or a brake lever, try to make sure it is not stuck, unlocking can be done by turning the wheel in the direction of the boom. Better not to allow it to be serviced and to leave this job skilled. Most of us, however, are jaw brakes, either geese or a so-called baby. Of course, we shouldn’t forget about the old cantilevers. Their arrangements and service are basically the same.

Dignity

  • the most powerful braking system for a bike;
  • work without loss of power in bad weather (snow and rain);
  • not a fear of “eights” and not wearing out the rims;
  • greater resource of discs and pads;
  • no need for service (for hydraulic);
  • heating on long descents of the brake disc, and not the wheel rim;
  • the size of the tires is not important;
  • attractive appearance.

disadvantages

Of course, like others, they have drawbacks. The most important of them is considered to be bad braking in bad weather and driving through puddles. True, it helps to somewhat correct the situation by briefly pressing the brake lever, which allows it to dry.

The braking force is also reduced if there is a “figure eight” on the wheel, as well as if the clearance between the block and the wheel rim is set incorrectly. In order to prevent this, it is recommended to periodically tighten the cable.

Another reason for the reduced braking performance of disc brakes is the wear of the rim and pad, which is accelerated when dirt gets on them. To eliminate this, they install special pads with grooves for removing dirt.

Prolonged braking, during which the rim heats up, also leads to rapid wear of the pads and damage to the tires. Some consider the disadvantage of v brake brakes is the fact that it is impossible to fit a tire that is more than 2.5 inches wide.

The listed disadvantages are not so significant for an ordinary cyclist, therefore, brakes of this type can be considered as the best choice.

This kind came from motorcycles and was at the beginning of its life as a brake used by extreme sportsmen. Today its niche has expanded, which is why it is found on touring bikes and budget XC bikes.

This type of brakes is subdivided, depending on the type of drive, into mechanical and hydraulic disc brakes. In the first case, the force is transmitted to the pads using a cable, in the second. the brake fluid filling the hydraulic line. Mechanical problems have the same problems as the v brake cable drive, but differ in improved braking.

How to Align a Mechanical Disc Brake on a Bike

How to adjust disc brakes on a stealth bike

How to install a new mechanical disc brake

  • We attach the brake lever to the handlebars so that it lies in the same plane as your forearm. If necessary, adjust the distance from the handle to the grip, at which, grasping the steering wheel with your whole hand, you could normally reach it with your index finger.
  • We install the adapter on the frame and tighten the bolts until fully tightened, alternately tightening each bolt.
  • We pass the cable with a jacket in such a way that it coincides with the places of its fixation to the frame.
  • We insert the cable into a special slot on the brake handle and refuel the shirt. Please note that when installing a new cable, the tension adjustment on the brake lever must be tightened completely minus 1-1.5 turns.
  • The position of adjusting the tension of the cable on the caliper is set in the same way as the brake lever. We pass the cable through the hole on the caliper, put it in the groove of the cable lock and, pulling, clamp the fixing bolt.
  • After that, we put the end cap on the end of the cable and squeeze it. This is necessary so that the cable does not fluff.
  • Next, we proceed to the adjustment, which is described below.

Disc / rotor

These terms are used interchangeably and in tandem to refer to a circular metal plate attached to the hub that the brake engages to slow the driver down.

Check the condition of the brake line for leaks

This item is exclusively for hydraulics. Before adjusting the hydraulic disc brakes of the bicycle, inspect the brake hose for damage (it is advisable to replace it, even if the damage is minor), and also check that there are no oil / brake fluid leaks at the joints of the hydraulic line with the caliper and the master cylinder. Another place where the brake fluid can poison is the rod going from the brake lever to the piston (if the cuffs are leaky). Well, after removing the brake pads, check the absence of leaks on the caliper.

Check rotor

First of all, we unscrew the brake rotor from the hub and check it for deformation. This can be done by placing it on a flat surface (glass, mirror, etc.) and inspecting it. If the rotor is loose, it should be aligned before adjusting the disc brakes. If the deformation is insignificant, then this operation can be performed when adjusting the brakes.

Which bike brakes are better to choose: rim or disc?

There are four types of bicycle brakes:

  • rim;
  • disk;
  • roller;
  • drum.

The last two types are now practically not used due to insufficient braking power. Except occasionally on city bikes. Roller brakes are not very popular due to the difficulties in their maintenance.

But drum brakes are familiar to many. They used to be installed on many touring bikes and were renowned for their reliability and durability. To brake, you had to pedal back. Such a system was not afraid of even the worst weather, did not require complex tuning, but it was not combined with the gearshift mechanism either. Therefore, for the new generation of bicycles, two types of brakes are now widely used: rim and disc. Which ones are better?

Comparison

For a long time, rim brakes had no competitors and were famous for their quality and reasonable cost. But lately they have a rival. disc brakes. They are considered more modern and reliable and more and more bicycle manufacturers are switching to them. To understand why, you need to consider their pros and cons.

  • reasonable price;
  • light weight;
  • light load on the spokes;
  • decent braking power;
  • simple construction;
  • easy replacement of parts.

All of the above applies to the most common of all types of rim brakes. V-brake. There are three other types of rim brakes: caliper, cantilever and U-brakes, but they are rarely used in touring, city and mountain bikes.

  • quick erasure of the rim and pads;
  • loss of braking power in bad weather;
  • strong heating in extreme riding conditions.

Disc brakes do not have all the disadvantages inherent in rim brakes.

  • higher power and smoother braking;
  • long term of operation;
  • independence from bad weather;
  • the possibility of extreme driving;
  • more attractive appearance of the bike.
  • higher cost;
  • heavy weight;
  • complex installation;
  • high load on the spokes;
  • rather complicated repair.

Thus, while disc brakes are more efficient, safer and more reliable, not everyone is ready to switch to them. The main stumbling block is their cost: they will have to pay much more for them than for rim.

There is only one conclusion: it all depends on the driving conditions you are accustomed to. If you only need a bicycle in the city or for quiet walks, then rim brakes can be dispensed with in order to save money. But if you like extreme driving, for which safety and reliability are first of all important, then it is better to stop at disc.
