Brake pad wear sensors are a safety critical product from ELTA Automotive.

The sensors monitor brake pad conditions and alert the driver once they wear below a predetermined level. The most advanced brake pad wear sensors are seen on German marques like BMW and Mercedes. These two-stage sensors have two parallel resistor circuits. One at a higher level and the second at the lowest acceptable level. Resistance in the sensor increases when the first circuit is broken and becomes an open circuit when the second circuit is broken. By working in conjunction with the first circuit of the brake pad wear sensor and considering wheel speed, brake pressure and temperature information; the vehicle’s dynamic stability control module (DSC) calculates the estimated brake pad lifespan and replacement intervals. This is often displayed to the driver via the car’s information system.

ELTA offers over 75 types of brake pad wear sensors from the VXPRO and Xevo brand programmes, catering for more than 3 million vehicles on the road.
