1, under normal driving conditions for each travel 5000 km on the brake shoe check once, not only to check the remaining thickness, but also check the wiper wear state, both sides of the same degree of wear and tear, the return is free, etc., found abnormal The situation must be dealt with immediately.
2, the brake shoe is generally composed of iron liner and friction material composed of 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, while 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 alarm tips to replace the shoe. To achieve the use of the limit of the shoe must be replaced, even if still can use for some time, will reduce the effect of braking, driving safety.
3, when changing 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.
