The brake sub-pump must be pushed back using a special tool. Do not use other crowbars to press back, which can easily cause the brake caliper guide screw to bend and make the brake pads jammed. After replacing the new brake pads, be sure to press the brakes a few times to eliminate the gap between the shoes and the brake discs.
After the brake shoes are replaced, it is necessary to run in 200 kilometers to achieve the best braking effect, and the brake pads that have just been replaced must be driven carefully. Brake pads are consumables in 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, brake pads usually wear out faster for vehicles that drive in urban areas than vehicles that are often driven on highways. Because cars that often drive in urban areas often stop and go, there are more chances of using the brakes. Vehicles driving on highways are likely to travel tens of kilometers before slowing down or stopping, and the probability of using the brakes is relatively reduced.
In addition, there will be a difference between the front brake pad and the rear brake pad replacement mileage. Under normal circumstances, the front brake pads of the front-drive car will wear faster than the rear wear, generally the front lining can be used 5-60,000 kilometers, the rear lint is 8-90,000 kilometers, if it is an A-class car or brake pads are relatively small, the service life will be shorter.
