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.

Abstract: A multi-disc brake assembly has a hub that is rotatable about an axis with at least a pair of discs supported on the hub for relative axial movement along the hub. The discs present braking surfaces for a plurality of friction elements to move into and out of frictional braking engagement therewith. A non-rotatable support structure releasably supports at least one hanger member to slidably support the friction elements. Releasing at least one hanger member from the non-rotatable support structure provides for removal of at least one of the friction elements from the disc brake assembly while the inner caliper portion remains attached to the outer caliper portion. Additionally, at least two bores may be formed in the non-rotatable support structure in generally axially opposed relation to one another. Piston members are disposed in the piston bores for movement toward and away from one another causing frictional braking engagement with the braking surfaces.
