Brake Pad Maintenance Method
- Jun 01, 2017 -

Brake pad are also called brake pad. In the car's braking system, the brake pad are the most critical safety parts, all the braking effect is good or bad brake pad play a decisive role, so that good brake pad are the protection of God and the car.

Brake lining (brake lining) generally by the steel plate, bonding insulation layer and friction block, steel plate to be coated to rust, coating process with SMT-4 furnace temperature tester to detect the temperature distribution of the coating process to ensure that quality. The insulation layer is composed of non-heat transfer material, the purpose is to heat. The friction block is composed of friction material, adhesive, brake is squeezed in the brake disc or brake drum on the friction, so as to achieve the purpose of vehicle deceleration brake. Due to friction, the friction block will gradually be worn, in general, the lower the cost of the brake pad wear faster.

Brake plate maintenance method

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. brake shoe is generally made 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, 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 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. Replace the original spare parts to provide the brake pad, the only way to make the brake pad and brakes between the best braking effect, wear the smallest.

4. When replacing the shoe, you must use the special tool to turn 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 pad stuck.

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

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

How to replace the brake pad:

1. Release the handbrake and loosen the hub screw that will need to change the brake wheel (note that it is loose and do not completely screw it down). Jack up with a jack. Then remove the tires. Before moving the brake, it is best to use a special brake cleaning fluid spray in the brake system to spray, to avoid powder into the respiratory tract, affecting health.

2. Remove the screw of the brake calipers (for some cars, simply remove one of them and then loosen the other)

3. Attach the brakes to the rope to avoid damage to the brake line. Then remove the old brake pad.

4. Use the c-type clamp to push the brake piston back to the inside. (Please note that before this step, first set off the hood, the brake oil box cover unscrew, because the top brake piston, the brake fluid surface will rise). Install the new brakes.

5. Pull the brake caliper back and the caliper screw to the required torque. Tighten the tires and tighten the hub screws slightly.

6. Lower the jack and tighten the hub screws.

7. Because in the process of changing the brake pad, we will brake the top of the piston to the inside, just start when the brakes will be empty. After a few steps on the just fine.
