Brake pads are consumables and will gradually wear out during use. When they are worn to the limit, they must be replaced, otherwise the braking effect will be reduced and even a safety accident will be caused.

Brake pads are related to life safety and must be treated with caution.
Most cars use the front disc and rear drum brake structure. Under normal circumstances, the front brake shoes wear relatively quickly, and the rear brake pads are used for a relatively long time. In daily inspection and maintenance, the following aspects should be paid attention:
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 brake pads, whether the degree of wear on both sides is the same, whether the return is free, etc. The situation must be dealt with immediately.
2. Brake pads are generally composed of two parts: iron lining and friction material. Do not wait for the friction material to wear out before replacing the shoe. For example, the front brake shoe of a Jetta car has a thickness of 14mm, and the replacement limit thickness is 7mm, including the thickness of the iron liner of more than 3mm and the thickness of the friction material of nearly 4mm. Some vehicles have a brake shoe alarm function. Once the wear limit is reached, the instrument will alarm to prompt the replacement of the shoe. The brake pads that have reached the limit of use must be replaced. Even if they can be used for a period of time, they will reduce the braking effect and affect the safety of driving.
3. When replacing, 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 disc be the best and the wear is minimized.
4. When replacing the brake pads, special tools must be used to push back the brake cylinder. Do not use other crowbars to press back hard, which will easily cause the brake caliper guide screw to bend and cause the brake pad to jam.
5. After replacing the brake pads, be sure to step on the brakes to eliminate the gap between the shoe and the brake disc, causing the first foot to not brake, which is prone to accidents.
6. After the brake pads are replaced, they need to run in for 200 kilometers to achieve a good braking effect. The newly replaced brake pads must be driven carefully.
