The daily maintenance of the brake pads
- Jul 14, 2017 -

The brake pads are usually made of steel plate, adhesive insulation layer and friction block. The steel plate is painted to rust, and the heat insulation layer is composed of non-heat transfer material. The friction block is composed of friction material and adhesive. The working principle of the brake is mainly from the friction, the use of brake pads and brake discs (drums) and tire and ground friction, the vehicle's kinetic energy into the friction after the heat, the car stopped. A well-established braking system must be able to provide a stable, adequate, controllable braking force, and has good hydraulic transmission and cooling capacity to ensure that the driver from the brake pedal of the force can be fully effective to the total pump And the sub-pump, and to avoid high heat caused by hydraulic failure and brake recession. Due to friction, the friction block will gradually be worn, in general, the lower the cost of the brake pads wear faster.

Daily use of the brake pads are good and bad points. Here are some of the more used to introduce more of the forklift.

  1

Semi-metal brakes, most of the cars when the factory brake pads are the same, this brake pads are relatively low, low coefficient of friction generally 0.38 shorter life expectancy, the disadvantage is prone to noise.

  2

Less metal brakes, this brake pads cost-effective, but most people are not easy to distinguish between this brake pads and semi-metallic brake pads the difference.

  3

Aramid copper fiber brakes, this formula brake pads superior to the above two, of course, the price and performance is also high, in the case of copper and aramid greatly improved the life of the brake pads and braking performance, the price also Slightly higher.

  4

High-end ceramic brakes: ceramic brakes on the market today, many different manufacturers do ceramic brakes are not the same, but also led to the excellent and poor ceramic fiber, this difference even after the manufacturers will know the quality of the use of Better than bad. The real ceramic brakes also contain aramid fiber, in terms of service life and brake pads are far superior to the above formula brake pads. Of course, the price is more expensive!

 

In the daily inspection and maintenance should focus on several aspects

1. Under normal driving conditions, 5,000 kilometers per kilometer 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, 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 in two parts, must not wait part of the friction material are not grinding only change the shoe. Some vehicles with brake shoes alarm function, once reached the wear limit, the instrument will alert the replacement of 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 pads, the only way to make the brakes and brakes between the best braking effect, wear the smallest.

4. When replacing the shoe, use a special tool to return 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 pads stuck.

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

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