Why do disc brakes on the bicycle creak, what should I do?

Probably, every cyclist faced with moments when the disc brakes on the bicycle are annoyingly creaking. What to do in such cases? Let's try to understand this issue together.

Why do disc brakes on the bicycle creak?

The cause of noise that causes discomfort during braking is usually hidden in the wrong grinding of the planes. In addition, the problem can be supplemented by contamination of surfaces in wet weather.

If the disc brakes on the bicycle, which just came off the counter of the sports goods store, do not immediately return it. To earn at full strength, the system must go through some lapping until an abrasive layer is formed on the rotor.

Bicycle disc brakes on the bicycle when braking and in those cases where the texture surface, which is required for effective braking, was incorrectly formed during running-in. In this case, the shoe can not reliably mate with the rotor, bouncing and creating omissions.

The disc brakes on the bicycle creak when pits and uneven paths are formed on their surface. Thus, the system, which is responsible for timely stopping of two-wheeled transport, turns into a kind of a record, tuned to an annoying squeal.

Prevention

Often creak disc brakes on the bicycle after replacing the old system with a new one. To eliminate the effect, it is enough to accelerate at medium speed, then several times to brake.

Inexperienced cyclists after buying a new "iron horse" try to initially operate it in a gentle mode, carefully passing the slopes and only slightly dragging the brakes on the corners. Often, such actions lead to the formation of an uneven, texture pattern on the disks.

If the disc brakes on the bicycle creak, it is necessary to pay attention to their lubrication treatment. For these purposes, it is recommended to use a special lubricator. When using a chemical spray, you will have to endure annoying sounds for a long time until the system returns to normal. In addition, during the application of an aerosol lubricant, other functional elements and surfaces are likely to become contaminated, after which a stable layer of dust is formed.

In terms of prevention, it is worth paying attention to a number of recommendations:

1. It is necessary to maintain the bike clean, performing the cleaning of the brake system after each trip in wet weather. To do this, it is sufficient to use a solvent, white spirit or gasoline. The meaning of such actions is to increase the area of contact and increase the frictional force.
2. Regular regular cleaning of the shoes should be carried out. You can do this mechanically by carefully scraping the dirt with a knife or with the same sandpaper.

How to eliminate the scratch in the brakes? Tools and materials

To solve the problem, these devices may be needed:

• Technical napkins.
• Liquid for cleaning bicycle braking systems.
• Sandpaper of fine granularity.
• Protective gloves and goggles.
• Set of keys and screwdrivers.

Step-by-step instruction

When the rear disc brake creaks on the bike, you must do the following:

1. Remove the brake pads by removing the lock pin.
2. Remove the brake rotor from the wheel.
3. Clean the disc using a special liquid, then wipe with technical napkins.
4. Gently grind the disc clean with fine-grained sandpaper, evenly removing the top layer in a circular motion. As a result, the contacting surfaces of the disk brake system should become as flat as possible.
5. After achieving the desired result, wipe the disc thoroughly with a clean piece of moist material or use the same napkins.

Brake shoes are treated in the same way. All the elements of the braking system are dried dry and placed in a clean place. Then the rotor is mounted back onto the wheel. It is recommended to carry out the operation in gloves.

After installing the brake pads, the locking pin returns to its original position and the system is ready for operation again. In conclusion, in order for the brakes to return to normal, it is necessary to ride a few times on a bicycle, accelerating at a speed of about 20 km / h, then stopping abruptly.

How to brake correctly?

To ensure a timely stop, an effective adjustment of the rear and front disc brakes should be performed. It is not necessary to weaken the front system, fearing a coup during braking. It is only necessary to learn how to properly use the stop, which can be done by performing maneuvers at different speeds.

As for the rear brake, it is recommended to use it in sharp bends, as turning the steering wheel and getting into the saddle is quite difficult, relying on the front system.

Do not simultaneously clamp the rear and front brakes. First you need to try to learn to perform a stop at a small speed, gradually increasing it. Only in this way can you determine the optimum pressure on the handle, depending on the situation.

Learning to safely brake jerks allows alternate use of the rear and front systems. Feeling the sliding of one wheel, it is necessary to stop the second one to a complete stop. Never worth to jump off a bicycle or put your feet forward, trying to increase grip on the surface.

Conclusion

After considering the main reasons for which there is an unpleasant scratch when braking, it becomes much easier to fix the problem. Carrying out the above actions in exact sequence allows you to spare the disc brakes from annoying squeaks, yelps, squeaks and other unpleasant sounds. Proper operation of the system, keeping it clean and performing periodic preventive maintenance allows you to ensure your own safety and enjoy riding in any conditions.
