What to do if the bicycle brake will sound, and what to do if the bicycle brakes when there is a sha

Kindness. If it's a V-brake, you look at the caliper, there's a very small screw on the side. You see if the brake pad is rubbed on the circle, take a closer look, which brake pad is wiped, and tighten the screws on the caliper of the brake block, and the screws on the caliper on the opposite side of it can be loosened slightly.

It's good to tune it this way.

Remove the brake pad, which is what we usually call the brake skin, and check whether there is a foreign object embedded in it, which is the main cause of the sound, and it will hurt the rim for a long time.

If your rim or brake pad is stained with oil, you need to use alcohol to clean the brake pad and rim.

There are many reasons for this, it will go off when it's cold or when there is water on the brakes, and this doesn't affect anything, it's just a matter of cold and hot brakes

Is it a mountain bike? This kind of car will sound as soon as the brakes are braked, and there is no way to do it.

Go to the place where you bought the car to repair it, the brake problem can be big or small. You try to put transparent glue on the contact surface of the brake.

There will be car repairs in the Giant store, I don't think it's a problem, my cars are like this at home.

But I'm not a car repairer after all, so it's better to ask.

You try to put transparent glue on the contact surface of the brake.

The contact between the brake pad and the brake wheel is not good, just use a section, and the friction contact between the two is even.

There are foreign objects on the contact surface of the film and disc.

Abnormal brake noises can be caused by incoming pads or dirty brakes, so be careful when oiling your bike. Disc brake cleaning usually requires removing the entire disc from the bike first, and replacing the disc in time if it gets wet. If there is a foreign object on the disc, wipe it with alcohol.

The installation process of the new lingling tablets must be done with care to ensure that they are correct. Improper installation methods and locations can greatly affect brake performance. The best way to secure the lintel is to drive down the road at a low speed and hold down the brakes. Repeat this step a few times to ensure the installation is in place.

When braking, the lever will bounce or make a serious noise, and if the disc is slightly bent or even grooved with the naked eye, it means that the disc has been deformed. It is not advisable to force the use of a wrench or vice to calibrate, and the uncontrollable force of human hand power will lead to greater damage to the disc, so it is recommended that the rider go to a professional maintenance point for replacement.

If it is not caused by the deformation of the disc, you need to adjust the position of the clamp so that it is in the middle of the frame to ensure the gap between the disc and the disc.

One: First of all, the two M6*18 screws on the caliper are semi-locked.

2: Press the brake handle to the locked state.

Three: Lock the two M6*18 on the caliper.

Remove dust from the brakes and inspect the individual parts for damage.

There are the following solutions to the abnormal noise when the disc brake of the mountain bike brakes

1. Disc brake deformation: similar to the long-distance downhill in summer, the disc brake deformation is caused by high temperature and overheating for a long time. Symptoms include the platter rubbing against the incoming disc and making a noise when it rotates.

Solution: Use a platter wrench to gently calibrate the platter if there is a friction somewhere between the wrench and the platter. The disc is seriously deformed and needs to be replaced in time.

2. The caliper is not debugged to the best state: at present, the mainstream fixing method of the mountain bike disc brake seat is the A-pillar direct installation, but the screw hole is easy to slip. Some of them are installed with the old-fashioned B-pillar adapter seat, so you don't need to worry about slipping wire, but the installation position of the adapter is troublesome.

If the clamp is not installed in place, it will directly cause the disc to rub against the incoming plate.

Solution: Use a 5mm Allen wrench to loosen the clamp fastening screws (remember not to loosen too much, just keep the clamp moving), then fine-tune the clamp to keep the same distance between the incoming pieces as much as possible, and then tighten the screws and turn the wheel. If you find that the platter is still rubbing, repeat the previous steps.

3. The incoming piece is locked and does not rebound: when disassembling the wheel, the disc block is mistakenly not put back in. If you accidentally pinch the brake at this time, it will directly cause the incoming piece to lock up and not rebound.

Solution: When removing the wheel, you need to put the disc stop back in time to prevent the incoming disc from locking.

The bicycle brakes loudly, mostly caused by uneven friction between brake components and skidding.

Here's how to fix it:

1. The drum brake system can be solved by sandpaper grinding the brake pad.

2. The V brake and C brake system can be solved by scrubbing the brake pad and rim with neutral cleaning agent.

3. The disc brake system can be solved by scrubbing the brake disc and the ring plate with alcohol or detergent. (or it may be a piece that is badly worn and needs to be replaced).

The disc brake squeaks when the bike brakes, how to deal with it?

Hello, thank you for your question, how to deal with it: 1. The brake disc fell into a small stone, and the sound caused by friction was taken out if observed. 2. The friction sound between the brake pedal cable and the floor or engine compartment partition, if there is contact friction, lubricate it.

3. Observe and measure the wear of the brake pads, and replace the brake pads if necessary4. If none of the above, remove the tires and check the brake discs.
