Maintenance methods

The normal driving conditions of every 5000 kilometers to the brake shoe inspection, not only to check the remaining thickness, but also to check the state of the hoof wear, the degree of wear on both sides is the same, the return is free and so on, found that abnormal conditions must be dealt with immediately. For example, the Jetta's front brake shoe, the new film thickness of 14 mm, and the replacement limit thickness is 7 brake lining roll mm, including 3 mm more iron liner thickness and nearly 4 mm of friction material thickness.

Brake shoes are generally composed of iron lining plate and friction material, must not wait for friction material parts are not worn before the replacement of the hoof piece. Can not be hard to press back with other crowbar, so easy to lead the brake clamp guide screw bending, so that the brake piece card die.

After the replacement, must step on a few feet to brake to eliminate the gap between the shoe and brake disc, resulting in the first foot did not brake, prone to accidents.

Replace the original spare parts to provide the brake pads, only in this way, the brake pads and brake disc between the best braking effect, wear the smallest.

The replacement of the hoof film must use a special tool to the brake pump top back. Some vehicles with brake shoe alarm function, once reached the wear limit, the instrument will be alerted to change the hoof piece.

After the replacement of the brake shoes, the need to run 200 km to achieve the best braking effect, just changed the hoof piece should be cautious driving. To reach the use limit of the hoof piece must be replaced, even if it can be used for a period of time, will also reduce the braking effect, affect the safety of driving
