How long is the brake shoe replacement cycle?

Brake Shoes (Brake Shoes) refers to the Brake CAM or push rod is pushed out of the force, the expansion of the Brake Shoes or Brake action of the accessories, such as the shape of a single piece or half moon.

Most cars use front disc and rear drum brake structure. In general, the wear of front brake shoes is relatively fast, and the use time of rear brake shoes is relatively long. The following aspects should be paid attention to in daily inspection and maintenance:

1. Under normal driving conditions, check the brake shoes every 5000 kilometers. Not only should we check the remaining thickness, but also check the state of shoe wear, whether the degree of wear on both sides is the same, whether the return position is free, and so on.

2, brake shoe is generally composed of iron lining plate and friction material two parts, must not wait for friction material parts are worn out before replacing shoes. For example, audi A6L car front brake shoe, the thickness of the new film is 14 mm, and the replacement of the limit thickness is 7 mm, including more than 3 mm of iron lining plate thickness and nearly 4 mm of friction material thickness. Some vehicles have a brake shoe alarm feature that will alert you to replace the shoe once the wear limit is reached. The shoe that has reached the limit of use must be replaced, even if it can still be used for a period of time, it will reduce the effect of braking and affect the safety of driving.

3. Replace the brake pads provided by the original spare parts, only in this way, can make the braking effect between the brake pad and the brake disc better, less wear, choose the integrity of the quick repair professional shop is more reliable.

4. When replacing shoes, special tools must be used to push back the brake sub-pump. Do not use other crowbars to hard press back, this will easily lead to brake caliper guide screw bending, brake pad jammed.

5. After replacing the shoes, be sure to step on several brakes to eliminate the gap between the shoes and the brake disc, resulting in the first foot no brakes, prone to accidents.

6. After the replacement of brake shoes, it is necessary to run in 200km to achieve the best braking effect. The shoes that have just been replaced must be driven carefully.
