Brake Pad Wear

This lamp illuminates when the vehicle's front disc brake pad linings have worn to the point of replacement. When this occurs the front brake linings should be inspected and/or replaced along with the sensor. Once this indicator lamp has illuminated the sensor must be replaced as its integrity has been compromised. The sensor is mounted to the inner disc brake pad lining.

The LH and RH brake pad wear sensors are wired in series to ground. The gauge cluster supplies battery power to the circuit. As the front disc brake pad linings wear to the point of replacement, a spring type bridge in the sensor separates, opening the circuit. This signals the gauge cluster to ground the indicator lamp, warning the driver to have the brakes inspected.
