The wear rate of the brake pad is related to the number of times it is used and the pressure it is subjected to. When designing the car, the inertia of the brake will be taken into account, so when braking, the rear brake pad will start first, which is equivalent to pulling the car up, because the front brake pad will lag behind for a few milliseconds, so there will not be too much impact. In the process of low-speed and slow braking, the rear brake pad will stop completely. If the front brake pad is in front, it is likely to stand upside down (raise your head) due to inertia during emergency braking, Therefore, the service life of the front brake pad is more than half that of the rear brake pad. The rear brake is the main brake, which is stronger than the rear brake in terms of brake and braking time.

Another important reason is that when adjusting the chassis and brakes, in order to make the braking force better, the manufacturers will not make the passengers feel a rush and stop. Therefore, many people who like comfort will notice that the wear of the rear baffle will be greater than that of the front in order to better brake. For those who love driving and slamming on the brakes, their front baffle will be worn out.

3. Automobile brake pad, also known as automobile brake skin, is a friction material combined with the brake drum or brake disc of the wheel. In this material, the friction lining plate and friction lining block are subjected to external pressure to produce friction and slow down the vehicle. Generally, the brake is composed of steel plate, adhesive insulation layer, friction block, etc. the steel plate needs to be sprayed to prevent rust.
