How To Apply The Brakes On A Speed Bike

Conclusion

Adjusting the brakes is not often required, but you can significantly save on it by doing everything yourself. In addition, it is not difficult even for sporty disc types with hydraulics. The main thing is to be careful and observe the golden rule. you should not save on your health, which is very easy to lose, using faulty or poorly adjusted brakes.

How to set up rim brakes

Vibrators are NOT losing popularity. Ease of maintenance, cheap consumables and unpretentious operation. an excellent option for those who use a bicycle primarily for moving, without extreme and overloading.

The principle of operation is elementary. when pressed, the brake lever pulls the cable (G), which moves the brake levers (I), presses the pads (J) attached to them against the wheel rim. When the handle is released, the levers return to their original position, installed on them by springs. In this article, we will analyze how to set up and adjust rim brakes:

Adjusting the rim brakes

Mountain bikes use a v-brake braking system. on its example, we will consider the principles of tuning, since it is also available on second bicycles with rim brakes. The difference can only consist in a different arrangement of bolts and screws, which will need to be tightened / tightened.

Note: it is important to observe three main rules:

  • Pads must be parallel to the rim;
  • The gap between the rim and the block should NOT be more or less than 1 mm;
  • The pads should be symmetrical in relation to each other.

How to achieve these guidelines when adjusting rim brakes on a bicycle:

  • You need to find a hex nut. it fixes the pads. To loosen it and set the brake pads in the desired position, you need to press the brake lever and watch how the pad touches the rim. By releasing the brake lever, the shoe can be set to the desired position. it moves up, down and at an angle.
  • The distance between the block and the rim of the wheel should not be more than 1 mm, although in some models of bicycles there are also 2-3 mm. exact information about a particular vehicle can be obtained either from the instructions for it or on the Internet for technical characteristics. It should be noted that braking of the wheel should occur even with the minimum pressing of the brake lever. That is, if the wheel stops only when the brake lever is fully pressed “all the way”, then this is incorrect.

After carrying out all the specified work, it is imperative to check the operation of the brake system. First, this is done at idle speed. lift the front wheel up, spin it and press the handle sharply, then do the same with the rear wheel. The next step is to check the operation of the brake system “in action”. sit on the bike and ride 3-5 meters, braked sharply. If the bike stops even when the brake lever is pressed to a minimum, then the system has been serviced correctly.

Disc brake adjustment

Disc brakes are rare items for adjustment or maintenance. Nevertheless, they sometimes have to be dealt with. Consider how to set up the brakes on a bike with a rotor and caliper.

We set the levers symmetrically

For the left and right shoes to wear evenly, they must be at the same distance from the rim. The tension of the springs on the brake levers is adjusted. To equalize the force that returns the left and right brake levers to their original position, we use the adjusting bolts located at the base of the levers.

Twisting the bolt clockwise we tighten the spring, unscrewing it loosens it. Pressing and releasing the brake, we check the uniformity of the removal of the pads from the rim. Tighten the bolts on the left and right sides until the pads will not move the same distance with the brake lever released.

Checking the reaction of the pads

When the brake lever is released, the gap between the pads and the disc should NOT exceed 2 mm on both sides.

To check the need for adjustment, turn the brake drum clockwise with the lever pressed and free.

Before replacing the brake cable on a bicycle, check the operation of the pads:

How To Apply The Brakes On A Speed Bike
  • The pads are in close contact with the disc (rim). adjustment is NOT required, the brake conductor is in normal tension.
  • The pads do not reach the disc. the cable length is shortened to the required level.

When pressed down on the lever, the pads must make firm contact with the disc or rim and stop rotation.

  • The brake cable must be adjusted so that when the lever is released, the wheel rotates freely and does NOT catch the pads.
  • When the lever is pressed, the position of the brake pads should not exceed 2 mm, and the lever rests against the handlebar.
  • If the lever is unbalanced and rests against the handle, it is necessary to pull the cable.

    Basic nodes to check

    Things to check before adjusting disc brakes?

    • Handle position. Its customization for hydraulic devices is also available.
    • The rotor if damaged or damaged. If there are chips, then no adjustment will help.
    • Transmission status (cable or channel).
    • Pads in a brake machine (caliper).

    The hydraulic drive is a rare guest in budget models. It is still used mainly by professionals. Adjusting the brakes on a hydraulically actuated bicycle is not very different from the mechanics and can be used. Unlike mechanics, hydraulics require work with brake fluid. Especially in winter, when it is necessary to bleed it to increase the pad travel.

    There are other problems in mechanics. There it may be necessary to adjust the pad pressing angle. Similar to rim options, it must be strictly parallel to the rotor. This increases the life of the brake system.

    Disc brakes have to be adjusted to the caliper. Adjustment steps:

    • We fix the wheel exactly in the same position as we will drive. This is important for the position of the hub and rotor.
    • Loosen the bolts that fix the caliper literally by a millimeter so that it can move, but not fall.
    • Squeeze the brake handle. The caliper falls into place.
    • Checking the clearances after releasing the brake lever.
    • We tighten the bolts or move the brake machine.
    • If the machine no longer moves freely, we work with the bolts Alternately, shift its tension of one or the other bolt.

    Checking the condition of the brakes

    First of all, we “unfasten” the brake, as shown in the photo.

    Check how the cable (G) moves in the shirt (A) by pressing and releasing the brake lever and pulling the cable back with your finger. the movement should be free, without delay. If the cable pulls hard, it may be damaged, the shirt or cable guide (C), or inside the jacket or cable guide of accumulated dirt. They must be removed and cleaned or replaced.

    Check the condition of the pads (J). They must show grooves for the drain of dirt (pads must not be smooth). Worn pads without grooves must be replaced. Check that the pads are complete with washers and that they are correctly installed.

    Observe the order of washers when installing new pads.

    Brake levers (I) Should pivot freely in their seats and spring apart after compression. If the movement is difficult, the brake during operation may get stuck in the closed position and rub with the shoe on the rim. In this case, you can remove the levers from the seats, clean and lubricate the contact points and reinstall.

    When installing, make sure that the protruding pin on the lever is in the hole on the frame, and that the hole on the left and right of the lever is the same.

    Shoe position and tilt adjustment

    After loosening or completely unscrewing the pad fixing screws, they can be shifted in any direction.

    This adjustment should be done, not removing the wheels, in order to clearly position the shoe. So, how should the block stand:

    • The block should be at the level of the rim, not a millimeter beyond it.
    • When checking for clearance from either side, the block should be in both the braking position and in the open position parallel to the rim.
    • When spinning the wheel, the block must be pressed exactly along the rotation vector. deviation from it will lead to damage to the brakes.

    After installing the pads in accordance with these conditions, the screws are tightened, the brakes are checked.

    Disc hydraulic brake

    So, the winner of the rating. It is hydraulics that rules the world of brakes. How does this system work? There are handles, there is a disc and there are braking elements. They are connected together by rubber tubes, inside of which is oil, or, as it should be said, brake fluid. What are its pros and cons? The hydraulics are responsive to every pressure. It can be said to instantly transmit pressure. That is why many athletes and extreme sportsmen use hydraulic disc brakes on their bikes. After all, the accurate transmission of sensations helps to win important seconds. The hydraulic brake firmly compresses the metal disc so that, when pressed hard, the rider can literally fly out of the saddle. But, like everyone else, hydraulics have their negative sides.

    First, the high cost. This, of course, is a dubious minus, because this system is bought NOT by ordinary amateurs, but by professionals. Second, the fix issue. Yes, the hydraulics are simply impossible to fix yourself. The slightest upset. and a trip to the workshop is guaranteed. And again, repairs will cost a pretty penny. Parts of the system, such as tubes, are not very reliable. If this part ruptures, brake fluid will escape. Therefore, brakes can only be done with your feet. Adjusting hydraulic brakes on a bicycle is tricky. This, if possible, it is better to entrust the master.

    Security issue

    Safety comes first! Yes, this rule is worth remembering every time you want to ride a bike. After all, many “ordinary” walks end with injuries.

    Self-adjusting the brakes on the bike

    Riding a bike is an incomparable pleasure. A constant wind in your hair, a feeling of complete freedom and independence, besides, cycling can replace constant trips to the gym, it’s no secret that riding a “two-wheeled” affects absolutely all muscle groups. First of all, legs, back, arms, abs. all this is maintained in an active tone thanks to cycling. The benefits of a bicycle cannot be minimized. But in order to enjoy walks from day to day, you need to take care of your “horse”. Preventive maintenance includes brake adjustment.

    Defective brakes

    Bad brakes are every cyclist’s problem. I don’t really want to carry out checks before every trip. It is tedious and time consuming. But here’s the problem. it’s necessary. A routine brake check can save lives and health. Adjusting the brakes on a bicycle is a painstaking task. Therefore, it is so important to be able to do it right.

    How to check and adjust the brakes

    There are clear instructions for checking and adjusting the brake system of a bicycle. If you adhere to it, then the whole process will take little time and will be effective.

    Procedure for checking and adjusting the brake system of a bicycle:

    • Dry brake test. It is necessary to raise the front wheel and, having unwound it, press the left brake lever. If the wheel comes to a sudden stop during this test, the braking system is in order and no maintenance is required. It is worth considering one nuance. if the brake lever touches the steering wheel, then you just need to pull the cable. The operation of the rear wheel brake system is checked in the same manner. To tighten the cable, you need to use curly bolts. just tighten them a little and, if only minor adjustments are required, this will correct the situation. It often happens that such a minimum adjustment does not work. in this case, we look at where the end of the cable is on the bike (it is always longer than necessary in advance), unscrew the bolt that holds it. It remains only to tighten the pliers part of the cable and tighten the bolt, applied Possible force.
    • Checking the brake pads. After the brake levers have been tested, the condition of the brake pads should be carefully examined. However, the order of action can be changed. first work with the pads, and then with the handles.

    The setting of the brake system for rim and disc types is different, since different rotating mechanisms and pads are used.

    Removing the brakes

    We go through the following steps:

    • Opening the brakes, under force Removing the cable jacket from the holder.
    • Unscrew the screw fastening to the frame.
    • Removing the brakes.
    • We unscrew the pads fixing screw, if work with pads is required.

    It is very important in the last step NOT to lose the correct sequence of washers. They come in pairs. convex and concave. Further adjustment depends on their settings.

    Disc mechanical brakes

    Everything is on the rise. And as you might guess, disc brakes are second in the list of systems of this type. What changes can be seen here? All the same levers, the same metal cables. Only the brake itself is changed. The disc is now bolted to the bicycle wheel. Nearby are two clamps with pads. Yes, the disc wheel is in direct contact with the clamps.

    This innovation increases grip. Now, if you hold down the lever, the wheel will not spin. This is why disc brakes are used on sport bikes. With it, the braking distance is halved. And this is what needs to be achieved. Adjusting disc brakes on a bicycle is different from the technique of adjusting rim brakes. Therefore, it can be difficult to drive all your life on V-breaks, and then switch to disc brakes. After all, you will have to learn to configure this system again.
