Abstract
A brake assembly that includes a caliper that has a guide bore, a brake carrier, a guide pin having a guide sleeve, and a lock arrangement. The lock arrangement has a friction element and is operable to selectively apply a force to the friction element to increase friction between the guide sleeve and the guide bore and inhibit relative sliding between the caliper and the brake carrier.
Claims19
A brake assembly comprising:
- a caliper that has a guide bore;
- a brake carrier arranged to receive a brake pad;
- a guide pin comprising a guide sleeve secured to the brake carrier, the guide pin defining an axial direction and being received within the guide bore of the caliper, wherein the caliper is slidable relative to the brake carrier along the guide sleeve;
- and
- a lock arrangement at least partially interposed between the guide bore and the guide sleeve, the lock arrangement comprising a friction element, wherein the lock arrangement is operable to selectively apply a force to the friction element to increase friction between the guide sleeve and the guide bore and inhibit relative sliding between the caliper and the brake carrier in the axial direction when a braking operation has ended and the brake pad is spaced apart from a rotor,
- wherein the friction element is configured to be deformed by the force applied by the lock arrangement, wherein the friction element is configured to be compressed in the axial direction and expanded in a radial direction by the force applied by the lock arrangement.

A brake assembly comprising:
- a caliper that has a guide bore;
- a brake carrier arranged to receive a brake pad;
- a guide pin comprising a guide sleeve secured to the brake carrier, the guide pin defining an axial direction and being received within the guide bore of the caliper, wherein the caliper is slidable relative to the brake carrier along the guide sleeve;
- and
- a lock arrangement at least partially interposed between the guide bore and the guide sleeve, the lock arrangement comprising a friction element, wherein the lock arrangement comprises a retaining cage disposed adjacent to the friction element, wherein the retaining cage further comprises an axially fixed element and an axially movable element, wherein the friction element is located between the axially fixed element and the axially movable element;
- wherein the lock arrangement is operable to selectively apply a force to the friction element to increase friction between the guide sleeve and the guide bore and inhibit relative sliding between the caliper and the brake carrier, wherein when the lock arrangement is operated, the axially movable element is moved towards the axially fixed element to apply the force to the friction element;
- and
- wherein the friction element is configured to be deformed by the force applied by the lock arrangement, wherein the friction element is configured to be compressed in the axial direction and expanded in a radial direction by the force applied by the lock arrangement.
