Brake shoe commonly known as brake pads, brake shoes refers to the role by the amount of brake cams or putter is pushed out to suppress brake brake function of the brake, the shape of such as half-moon.

Under normal driving conditions, the brake shoe shall be inspected once every 5,000 km. Not only the remaining thickness but also the wear status of the shoe, the degree of wear on both sides of the shoe and the degree of wear on both sides shall be checked. Deal with it immediately. Brake shoes are generally composed of iron lining and friction material of two parts, must not wait friction parts were worn out before the replacement of the shoe. For example, Jetta front brake shoe, the new film thickness of 14 mm, and the replacement of the ultimate thickness of 7 mm, including more than 3 millimeters of iron liner thickness and nearly 4 mm friction material thickness. Some vehicles with brake shoe alarm function, once reached the wear limit, the instrument will prompt the replacement of the shoe alarm. To reach the limit of the shoe must be replaced, even if can still be used for some time, will also reduce the effect of braking, driving safety.

Replace the original spare parts to provide the brake pads, the only way to make the braking effect between brake pads and brake discs best, wear the least. Replace the brake shoe must use special tools to brake the top of the sub-pump. Can not use other crowbar hard pressure back, so easily lead to brake caliper guide screw bending, brake stuck. After replacement, be sure to step a few feet brakes to eliminate the gap between the brake shoe and brake disc, resulting in the first leg without brake, prone to accidents.

There must be some clearance between brake shoe and brake drum. Brake shoe clearance does not meet the requirements, will directly affect the braking performance of the car. If the gap is too large, making the brake hysteresis increases, the braking distance increases, driving safety reduced; gap is too small to brake can not be completely lifted to increase the driving resistance, accelerated brake drum and shoe wear.
