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. The situation must be dealt with immediately. 2. The brake shoe is 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 the Jetta (Gallery Forum) 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.

2. The brake shoe is 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 the Jetta (Gallery Forum) car, the thickness of the new piece is 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 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 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. Special tools must be used to push back the brake cylinder when replacing the shoe. 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 replacement, 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 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.
