The brake principle of the disc brake

When the rider brakes, hold the brake handle, the brake oil in the brake pump will produce pressure, the liquid will pass the pressure through the pipeline to the piston in each wheel caliper, the piston then drives the caliper to clamp the brake pad and brake disc, thereby creating friction, so that the motorcycle slow down.

Therefore, the brake pads in the brake caliper clamp the circular brake disc when the driving rotates to achieve tire braking, the brake disc and the brake disc are not replaced for a long time, which will produce greater wear and tear, leading to the deterioration of the motorcycle braking effect, so it is important to master the relevant knowledge of the brake disc.

What is a brake disc

The brake disc, simply put, is a round plate, which also turns when the motorcycle travels. The brake caliper grips the brake disc and generates braking force, and the brake block grips the brake disc to slow down or stop. Brake discs brake better, but they are also more prone to wear than drum brakes.

Brake disc replacement mileage

In general, the brake block (that is, the two pieces of the brake caliper) needs to be replaced by about 20 to 30 thousand kilometers, and the replacement mileage of the brake disc is generally about 40 to 50 thousand kilometers. Of course, the replacement mileage is not completely absolute, but is determined by the owner's own driving habits (whether he likes to brake), road conditions, maintenance cycle and other factors.

When do I need to replace the brake disc

1. In addition to the driving distance mentioned above, if the brake block is severely worn and continues to be used, resulting in friction between the iron block of the brake block and the brake disc, the brake disc will soon be worn out of a deep groove, and it needs to be replaced immediately.

2. Although the brake block is not worn to the brake disc, due to long-term use, there is a deep groove on the brake disc, and when the depth of the deep groove on both sides exceeds 3 mm, the brake disc needs to be replaced.

3. Although the surface of some brake discs is smooth, they have been worn too thin, and the brake pump is rusty, and the brake block is also excessively worn, which is not only to replace the brake disc, but also to maintain the brake pump.

The daily maintenance method of brake disc

After the motorcycle rides a long distance, the brake disc will generate a lot of heat in the braking situation, so do not wash the car immediately after the motorcycle rides a long distance, should be turned off to reduce the surface temperature of the brake disc, to prevent the high temperature brake disc because of contact with cold water thermal expansion and contraction deformation. It is also necessary to prevent the stone from hitting the brake disc resulting in deformation, locking the wheel and forgetting to unlock the vehicle, which is also easy to lead to the brake disc deformation, when the brake disc is deformed, it will produce a single direction of friction sound.

In addition, the best way to improve the life of the brake disc is to maintain good driving habits and try to avoid emergency braking. The sediment on the brake disc should be diligent in cleaning, and often check whether the brake block is worn to the iron with the brake disc.
