Abstract: An electric caliper having a housing mounted adjacent a rotatable disc. First and second force applying elements support a friction element between the housing and the rotatable disc. An electric actuator is mounted in the housing and is operatively connected to the first and second force applying elements. The electric actuator is operable to move the first and second force applying elements and the friction element toward, and away from, the disc and cause the friction element to frictionally contact the disc. A method is also provided for applying first and second forces against a friction element in response to an operation of an electric motor. The first and second forces are applied with respective magnitudes so as to maintain a substantially constant wear between the edges of the first friction element.
