Car knowledge explains how to check and replace brake pads

Brake pads, Also known as brake shoes, are consumables that will gradually wear out during use. When the wear reaches the limit, it must be replaced, otherwise it will reduce the braking effect and even cause a safety accident. Brake shoes are related to life safety and must be treated with caution.

1. Under normal driving conditions, check the brake shoes every 5000 kilometers, not only check the remaining thickness, but also check the wear status of the shoes, whether the degree of wear on both sides is the same, whether the return is free, etc., and it is found to be abnormal The situation must be dealt with immediately.

2. The brake shoe is generally composed of two parts, an iron lining plate and a friction material. You must not wait for the friction material to wear out before replacing the shoe. For example, the front brake shoe of a Jetta car, the thickness of the new piece is 14 mm, and the replacement limit thickness is 7 mm, which includes the thickness of the iron lining plate of more than 3 mm and the thickness of the friction material of nearly 4 mm. Some vehicles have a brake shoe alarm function. Once the wear limit is reached, the meter will give an alarm to remind you 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 braking effect and affect the safety of driving.

3. When replacing, replace the original spare parts provided by the factorybrakeThe only way to make the brake pads andBrake discThe braking effect in between is the best and the wear is the least.

4. Special tools must be used to push back the brake cylinder when replacing the shoe. Do not use other crowbars to press back hard, as this will easily cause the brake caliper guide screw to bend and cause the brake pad to jam.

5. After replacement, be sure to step on the brakes several times to eliminate the gap between the shoe and the brake disc, causing the first foot to fail to brake, which is prone to accidents.

6. After the brake shoe is replaced, it needs to run in for 200 kilometers to achieve the best braking effect. The newly replaced shoe must be driven carefully. (Dahe Net)
