Brake Pads 29162

The composition of the auto brake pads

The braking system of the automobile is a device that forcibly decelerates or even stops the running car according to the driver's request, and at the same time keeps the speed of the vehicle traveling downhill stable. Brake pads and brake discs are important parts in the car's brake system. Its quality depends on the brake pads and brake discs, so good brake pads and brake discs are safe for driving.

The automobile brake pad is mainly composed of a back plate, a bonding heat insulation layer, a friction material layer, a sound absorbing sheet and an attachment. The friction material layer is composed of a friction material and an adhesive. When braking, the friction material rubs against the brake disc to generate a braking force, thereby decelerating the vehicle. The bonded thermal insulation layer is composed of a material having a low heat transfer rate for the purpose of heat insulation. Due to the friction between the brake pad and the brake disc, the friction material layer will be gradually worn out, so the friction material layer of the brake pad should be replaced in time after using the limit, otherwise the back plate will directly contact the brake disc, which will not only reduce the braking effect, It even caused damage to the brake disc or malfunction of the brakes.

Car brake pad installation

In case of abnormal noise in the vehicle brakes, first analyze the situation and then check to determine the cause of the problem. Do not blindly replace the accessories. According to the actual situation, the original car brakes have a high chance of scratching the original brake discs. This is not the case because of the original car parts. Many repair shops and drivers do not believe that the original brake pads are damaged. . Therefore, we need to check the new brake pads and replace them.

When installing the brake pads, we must first remove the bolts of the brake caliper with a wrench and a sleeve, and then remove the brake pads. Use a piston pump to press the piston to the fixed position, then install the brake pad on the brake caliper, install the new brake pad in place, and tighten the guide bolts to complete the installation. After installation, cover the reservoir lid, press the brake pedal a few times in the vehicle, and reset the brake. Then observe the brake fluid height, which is within the appropriate height range.

Car downhill braking

When the vehicle is going downhill, especially when it is downhill, don't use the brakes for a long time. This will easily lead to friction and overheating of the brake pads, which will cause the brake performance to drop. In order to prevent this, it is necessary to use the low gear downhill for manual transmission models. It is ok to use 3 blocks. For automatic cars, you can't refuel at the beginning of the downhill. You must keep the speed of the car slowly increasing. If necessary, use the brakes to control the speed.

The purpose of the car's downhill downshift is to use the engine to maintain a relatively low speed, which is due to the origin of the truck. Because the truck generally has a heavy weight and is used as a drum brake, if the brake is used too frequently when encountering a long downhill slope, it may cause the brake to overheat and cause a serious brake failure, so the truck is in addition to the downhill slope. In addition to using brakes to control the speed of the car, special attention is paid to the use of low-speed gears to control the speed.
