D1141 Brake Pads

Causes of partial wear of brake pads

The brake pads of the car are connected by two telescopic rods. When the car brakes, the brake pads rub against the brake discs. When the brakes are released, the two brake pads move along the telescopic rods to the sides and leave the brake discs. A common problem when using brake pads is partial wear. The following ceramic brake pad manufacturers talk to you about possible reasons.

The brake pads themselves and other external conditions can cause uneven wear on the brake pads. The common reason is that the brake pad material is not uniform. When the vehicle brakes, the left and right wheels are unevenly stressed. One side of the brake disc may be deformed, the brake cylinder is inconsistent, the car telescopic rod lacks lubrication, and the rod cannot be freely stretched. The outer sheet cannot leave the brake disc or the like. In case of encountering these problems, it is necessary to solve the problem in time. Do not let the brake pads eclipse affect the braking performance, otherwise it may cause unnecessary safety accidents.

Car brake jitter problem

When the disc brake is braked, the friction block presses the brake disc under the action of the brake pressure, and the friction between the friction block and the brake disc causes the vehicle to decelerate. If the surface of the brake disc is not flat or the thickness of the brake disc is not uniform, it will cause a change in the brake pressure and a change in the frictional force, resulting in fluctuations in the braking torque. Brake jitter is the low frequency vibration caused by the fluctuation of the braking torque.

The obvious feature of brake jitter is the sharp shaking of the steering wheel and the instrument panel, the vibration of the seat, and sometimes the pulsation of the brake pedal. In severe cases, the entire body is shaken. The general situation of brake jitter occurs when the vehicle runs at a high speed and applies medium-intensity braking. When the vehicle speed drops to a certain value, the jitter starts to appear. As the vehicle speed decreases, the jitter increases. When the vehicle speed drops to a certain characteristic speed, the jitter amplitude reaches the maximum and the vehicle speed decreases again. The jitter is reduced until the jitter drops after dropping to a certain speed.

The role of car brake pads

Any vehicle with all mechanical equipment and motion must have a brake or transmission. Friction materials are a key component of such brakes or transmissions. Its main function is to absorb or transfer power through friction. If the clutch plates transmit power, the brake pads absorb kinetic energy. They enable mechanical equipment and a variety of motor vehicles to work reliably and reliably. Although the brake pads of the car are small, they ensure the safety of the brakes of the car.

Automobile brake pad is a kind of polymer composite material. It is composed of polymer binder (rubber and resin), reinforcing fiber and friction modifier, and other compounding agents. It is made by a series of production and processing. product. Automotive brake pads are one of the important components of the car's brake system. They are components that protect the safety of vehicles and personnel. Therefore, we need to regularly inspect and maintain the brake system during daily use.
