What matters should the replacement and maintenance of brake pads pay attention to?

Under the normal driving conditions of the car, every 5000 kilometers should be checked on the brake shoes, not only to check the remaining thickness of the brake pads, but also to check the wear state of the brake pads, whether the degree of wear on both sides is the same, whether the return is free, etc., found that the abnormal situation must be dealt with immediately. Brake shoes are generally composed of iron lining plate and friction material two parts, be sure not to wait for friction material parts are worn away before replacing the shoe. Some vehicles have brake shoe alarm function, once the wear limit has been reached, the meter will warn to replace the shoe. The shoe that has reached the limit of use must be replaced, even if it can be used for a period of time, it will reduce the effect of braking and affect the safety of driving.

Special tools must be used to push the brake pump back when replacing the brake pads. Do not use other crowbars to press back hard, which can easily cause the brake caliper guide screw to bend, so that the brake pad stuck. After replacing the new brake pads, be sure to step on a few brakes to eliminate the gap between the shoe and the brake disc. After the brake shoe replacement, it is necessary to run 200 kilometers to achieve the best braking effect, and the newly replaced brake pads must be driven carefully. Brake pads are consumables in the car parts, which will gradually wear out in daily driving, and must be replaced when the brake pads are worn to the limit, otherwise it will reduce the effect of braking and even cause safety accidents.

The service life of brake pads is also "different from person to person", such as the material quality of the brake pads themselves, the quality of the brake system, the driver's driving habits, the driving environment and so on. In general, often in urban vehicles, brake pad wear is usually faster than often on the highway vehicles. Because cars that often drive in urban areas often stop and go, the chance of using the brakes will be more. A vehicle driving on the highway is likely to walk dozens of kilometers before it needs to slow down or stop, and the probability of using the brake is relatively reduced.
