Servicing brake pad wear indicators, also known as brake pad wear indicators, which are standard on many modern cars, promises to be a highly demanded operation during brake system maintenance.

Road conditions, driving style, speed, weight of the transported load, the type of pads and discs used - all these factors affect the rate of wear, which creates some difficulties for drivers and auto mechanics in determining when to replace them with a new set. With the advent of the A.B.S. brand Warning Contact, brake pad wear sensor, this problem disappears. In addition, they help plan brake system maintenance and keep the brake pads in good condition for safety and complete vehicle control.

Additional functions of the brake pad wear sensor

The main elements of a A.B.S. brand Warning Contact, brake pad wear In addition to alerting the driver to a worn-out pad, they can also determine the mileage remaining for the pads. These sensors are also known as two-stage sensors. They have two resistive circuits that run parallel to each other in the sensor housing at different heights. When the first circuit is broken, the resistance in the sensor increases and the system calculates the amount of brake pad wear using inputs such as wheel speed, mileage, brake pressure, brake temperature and brake duration.
