Sensor, brake pad wear - 638 955 TOPRAN
- Part Number: 638 955
- Brand: TOPRAN
- Type: Sensor, brake pad wear
The frictional force is responsible for braking the vehicle. But over time, brake pads wear out, losing their original qualities. Therefore, it is important to replace them in a timely manner. Special sensors will help you find out when the time has come when new pads need to be installed. They will alert you when the brake pads are worn out.
Friction brakes are currently used on ground vehicles. Their work is based on the force of friction. In cars, this is implemented as brakes built into the wheels. They consist of stationary brake discs or drums. When friction or contact occurs, the kinetic energy of the vehicle is converted into thermal energy. As a result, its speed decreases. The car stops.

The functionality of the TOPRAN brand Sensor, brake pad wear
During operation, the friction linings are subject to wear. Their thickness decreases, the nature of inhibition changes. When the block reaches a thickness of approximately 3 mm, it is important to replace it. Otherwise, the wear of the braking device will increase. This is fraught with deterioration in braking. Reaching critical wear, sensors signal the need to replace the pads. The presence of sensors will allow you not to worry about the state of the brakes.
