ABSTRACT:
A brake actuator assembly includes a sensor mounted to a push rod which is in communication with a transceiver antenna. The sensor provides positional information of the push rod relative to the antenna. A clearance between a friction element and a rotating brake member is determined based on displacement of the push rod and known mechanical relationships within the brake actuator.
