Most car with front disc and drum brake structure, general front brake shoe wear relatively quickly, rear brake shoe uses a relatively long period of time, in the daily inspection and maintenance should be focused on in the following aspects:
1 under normal driving conditions every travel 5000 kilometers on the brake shoe check once, not only to check the remaining thickness, but also check the shoe wear condition, wear on both sides of whether the degree of the same, return whether to freely, found abnormal situation must be addressed immediately.
he 2 brake shoe is generally composed of iron lining plate and the friction material is composed of two parts, such as friction materials must not wear no part to replace the brake shoe. For example, the Jetta [overview picture Forum] vehicle front brake shoe, the film thickness of 14 mm, and the replacement of the limit thickness is 7 mm, including 3 mm multiple iron lining thickness and nearly 4 mm thickness of friction materials. Some vehicles with brake alarm function, upon reaching the wear limit, the instrument will alarm replacement shoe. To limit the use of the shoe must be replaced, even if still can be used for a period of time, also can reduce the braking effect, affecting the traffic safety.
3 replacement to brake, replace the original spare parts provided by the only way to make the brake pad and the brake disc brake effect best, minimal wear.
4 replacing the shoe pads must use special tools will brake branch pump top back. Do not use a crowbar hard pressed back, so easy to cause the brake caliper guide screw bending, so that the brake clamp.
5 after the replacement, must walk a few feet to eliminate the gap of brake, shoe pad and the brake disc, causing the first foot brake, prone to accidents.
The 6 brake shoe replacement after running 200 kilometers, required to achieve the best effect of brake, just change the shoe must be careful driving.
