5 frequent breakdowns of your bike brakes and how to solve them

The brakes of a bicycle is one of the components that are mismatch or suffer faults more frequently, especially when used very intensely. Both Zapata and Disco brakes. And these breakdowns require priority reparation due to the importance of security brakes for cyclist and bike handling. Obviously none want to end the bones on the ground due to an accident due to a failure in the braking system when we are lowering a mountain port or rolling along a path. Hence the convenience of Make a periodic review of your bicycle braking system. In this article we collect the most important breakdowns that may appear on the brakes of your bicycle in a recurring way. Also, we also indicate how to solve them quickly, or if on the contrary it is necessary to go to a mechanic due to their complexity.

1. The brake sounds a lot or squeaks

Brake discs with mud It is one of the most typical and frequent problems that have brakes, both disc and Zapata. On the former, small noises can be heard when the wheel has been turned without operating the suitcase. The most common cause is that the clamp is not well installed or badly tight, which causes the small channel that leaves the disk with one or the two pills. This can cause premature and unequal wear of the pills and obtain an irregular braking.

How to repair the breakdown

Identified the origin of the noise, it is time to challenge the screws to hold the clamp to the painting (or to the fork in the case of the striker) and relocate it, moving it slightly to make sure that disc and pill they do not touch and re -tighten it later. In the case of Zapata brakes, the brake bridge should be focused with the help of an Allen type key to separate the shoes from the braking track of the tire and both stop in unison.

2. annoying vibrations when braking

Cyclist taking curve Both in the disc brakes and in those of Zapata the vibrations appear in most occasions by defects on the braking surface. In the first it is the disc (which could be bent, poorly installed or dirty), and in the second the braking track of the tire (dirty or with deformations for blows or wear).

How to repair the breakdown

In the case of discs, you have to clean your surface well using soft soap and water, as well as visually check that when you turn it is not bent, examining the edge. If oscillations are seen in this one or cause friction with the pill you must check the tightening of the screws to the wheel bushing, because they may be challenged. In the case of bridge or zapata brakes, the same steps will have to This Velodrom Cycling Channe videol show you how to do it effectively) and verification of their status. If it is already very worn by the use, presenting a concave profile instead of straight, the time will come to discard the tire and install a new one.

3. Lack of touch in the brake handle

Cycling gloves This is a common symptom of fault or mismatch of your brakes. You squeeze the handle strong, hurrying its entire route, but the bicycle barely stops or does it after making a great effort with your fingers. The brakes accuse lack of touch and braking becomes uncomfortable or complicated.

How to repair the breakdown

The lack of brake touch may be due to the air inlet into the fluid circuit, in the case of hydraulic disc. Also to some mismatch of the handle route, which is possible to solve by pressing or challenging to obtain the appropriate to your needs. In the conventional brakes of Zapata or in those of mechanical (non -hydraulic) discs, the loss of touch forces to check the cable tension. But it may also be because the pistons of the clamp are very glued or dirty. From home you can try to disassemble the wheel and perform this operation, before throwing yourself to purged the circuit:
  1. With the wheel disassembled, it acts several times the handles until the pills are stuck.
  2. Enter the brake pad separator between them.
  3. Return the wheel and drive the handle several times to retire and align the pills.
If the problem persists, it is most likely that the braking circuit has air and you should do a purged operation. In This BTT globeros video They explain how to do it from home and the tools you have to use.

4. Little braking power

Enduro MTB If the touch when the brake is proceeding is good but it does not stop enough is that it may have lost part of its original power. The loss of average brake power can translate into handling problems in technical sections and difficulties to completely stop the bike, so it directly compromises the cyclist's safety.

How to repair the breakdown

It is a priority repair breakdown for its implications in cyclist's safety. The most common cause is the wear of the pills or poor condition of the brake fluid in the case of disc systems, and the wear of the shoes or the braking track in the case of bridge (shoes). A revision with purity of the system and change of pills, as well as replacement of shoes, can solve the problem.

5. Brake overheating

Cyclist with mountain bike Finally, it is quite frequent that when you go down with your mountain bike for a long and steep down the brakes lose some power due to the friction warming between the pills and the disc. This also happens in road cycling when we lower a mountain port and we have to act the brake in a constant way.

How to solve it

The best way to avoid overheating is Learn to use the brake properly not to stop continuously, using it only to correct the traced or lessen the speed before the technical step. But if still the brakes have been overheated and you do not get the necessary braking power, it is convenient to stop and pause to cool and recover their touch again. There are few cyclists who take advantage of the water of the drum or backpack to spray the disc and thus cool quickly. It is not a highly recommended practice, since the temperature difference between cold water and hot metal can end up damaging the disc and, in the long run, worsen the operation of the brakes. The most convenient in these cases is prevention: slowly and progressively stop, avoiding continuous use.
