Brake Pad Wear Sensor: Service and Repair
FRONT DISC BRAKE PAD WEAR SENSOR
The front disc brake system on this vehicle is equipped with an electronic brake pad wear indicator that illuminates the indicator lamp on the
instrument panel when the linings wear to a degree where replacement is replaced. The brake pad wear sensor is pressed into the inner brake pad and
connects to the vehicle wiring harness with a dual terminal connector mounted on the inner-fender well. The sensor consists of the following parts:
-
A plastic L-shaped housing with an integral circuit loop
-
A steel retaining button
-
A two-wire connector feed
When the linings have worn to the point of replacement the sensor makes contact with the rotor causing the plastic sensor housing to wear. Eventually
interrupting the circuit loop. This cause the indicator lamp on the instrument panel to illuminate. Once the indicator lamp has illuminated the sensor
must be replaced with the replacement of the brake linings and is not reusable.
