Abstract: A disc brake assembly including a caliper bracket, a caliper housing having an outer portion and an inner portion, the inner portion defining a piston bore therein, wherein the caliper housing is moveable relative to the caliper bracket, a caliper piston received within and extendable from the piston bore, an elastic element positioned relative to the caliper housing and the caliper bracket, and a disc rotor assembly including a hub and at least two rotors, each of the rotors having at least two friction surfaces, at least a portion of each of the friction surfaces being positioned between the outer portion of the caliper housing and the caliper piston, wherein the caliper housing moves relative to the caliper bracket when the caliper piston extends from the piston bore to engage the disc rotor assembly, thereby deforming the elastic element.

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.
