Abstract
Systems and methods are for monitoring a wear state of a disc brake for braking a rotor of a vehicle. The disc brake has a caliper configured to clamp opposing inner and outer brake pads onto the rotor. A primary wear sensor is configured to sense a combined thickness of the rotor, the inner brake pad, and the outer brake pad. A controller is programmed to calculate an estimated wear amount of the inner brake pad and an estimated wear amount of the outer brake pad based upon the combined thickness. In some embodiments a secondary wear sensor is included and the system is configured to calculate an actual wear amount of the inner brake pad and an actual wear amount of the outer brake pad based upon input from the primary wear sensor and the secondary wear sensor.
