Brake shoe is a consumable, in use will gradually wear and tear, when the wear to the limit position, must be replaced, otherwise it will reduce the braking effect, and even cause a security incident.

Brake shoes related to life safety, must be treated with caution.

Most of the cars used in the front plate after the drum brake structure, under normal circumstances the front brake shoe wear is relatively fast, after the brake shoe used a relatively long time in the daily inspection and maintenance should focus on the following few Aspect:

1. Under normal driving conditions, 5,000 kilometers per kilometer on the brake shoe check once, not only to check the remaining thickness, but also check the wiper wear state, both sides of the degree of wear is the same, the return is free, etc., found abnormal The situation must be dealt with immediately.

2. Brake shoe is generally made of iron liner and friction material in two parts, must not wait for friction material part of the grinding did not change the shoe. For example, Jetta's front brake shoe, the new film thickness of 14 mm, and the replacement of the ultimate thickness of 7 mm, which includes 3 mm more iron liner thickness and nearly 4 mm of friction material thickness. Some vehicles with brake shoes alarm function, once reached the wear limit, the instrument will alert the replacement of the shoe. To achieve the use of the limit of the shoe must be replaced, even if still able to use for some time, will reduce the effect of braking, driving safety.

3. Replace the original spare parts to provide the brake pads, the only way to make the brake pads and brakes between the best braking effect, wear the smallest.

4. When replacing the shoe, you must use the special tool to lift the brake cylinder back. Can not use other crowbar hard pressure back, so easy to lead to brake caliper guide screw bending, so that brake pads stuck.

5. After replacing the shoe, be sure to step on the foot brake to eliminate the gap between the shoe and the brake disc, resulting in the first foot without brakes, prone to accidents.

6. brake shoe replacement, the need to run 200 km to achieve the best braking effect, just change the hoofs should be careful to drive.
