Maintenance, editing and broadcasting of 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 situations must be dealt with immediately.
② Don't wait for the friction material to wear out before replacing the shoes. For example, the front brake shoes of Jetta have a new thickness of 14 millimeters, while the maximum thickness for replacement is 7 millimeters, including a thickness of over 3 millimeters of iron lining plate and nearly 4 millimeters of friction material. Some vehicles have a brake shoe alarm function, and once the wear limit is reached, the instrument panel will give an alarm to prompt for shoe replacement. The 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 braking effect 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 the brake discs be optimal and the wear be minimized.
④ When replacing the brake pads, special tools must be used to push the brake wheel cylinder back. Do not use other crowbars 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, it is necessary 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 must be driven carefully.
