Maintenance Issues With Brake Pads

Brake pads are a key safety component in the automotive braking system, and their performance is directly related to the braking effect of the car, which is closely related to the safety of the car. Therefore, daily maintenance of brake pads is particularly important. In daily inspection and maintenance, the following aspects should be emphasized:
① Under normal driving conditions, check the brake shoes every 5000 kilometers. Not only should the remaining thickness be checked, but also the wear status of the brake pads should be checked, whether the degree of wear on both sides is the same, whether the return is smooth, etc. Any abnormal situation must be dealt with immediately.
② Be sure not to wait for the friction material to wear out before replacing the shoes. For example, the front brake shoes of Jetta cars have a new thickness of 14 millimeters, while the maximum thickness for replacement is 7 millimeters, which includes a thickness of over 3 millimeters for the iron lining plate and nearly 4 millimeters for the friction material. Some vehicles are equipped with brake shoe alarm function. Once the wear limit is reached, the instrument panel will give an alarm to indicate the replacement of the brake shoes. Brake pads that have reached their limit of use must be replaced. Even if they can still be used for a period of time, it will reduce the effectiveness of braking and affect driving safety.
③ When replacing, it is necessary to replace the brake pads provided by the original spare parts. Only in this way can the braking effect between the brake pads and brake discs be optimal and wear be minimized.
④ When replacing brake pads, special tools must be used to push the brake cylinder back. Do not use other pry bars to forcefully press back, as this can easily cause the brake caliper guide screw to bend and cause the brake pads to jam.
⑤ After replacing the brake pads, be sure to apply a few foot brakes to eliminate the gap between the shoes and the brake disc, which may cause the first foot to not brake and lead to accidents.
⑥ After replacing the brake pads, it is necessary to run in for 200 kilometers to achieve the best braking effect. The newly replaced brake pads need to be driven with caution.
