Abstract
A disc brake assembly that includes first and second brake pads for contacting a rotor, a brake carrier for receiving at least the first brake pad, a brake caliper arranged to slide with respect to the brake carrier, and an actuating arrangement. The actuating arrangement is configured to selectively move the brake caliper and is electrically operated.
Claims20
A disc brake assembly for a vehicle, the disc brake assembly comprising:
- first and second brake pads operable to contact a rotor during a braking operation to slow the vehicle, the rotor having a central axis defining an inboard-outboard axial direction;
- a brake carrier that receives at least the first brake pad;
- a brake caliper arranged to slide with respect to the brake carrier in the inboard-outboard axial direction to clamp and release of the rotor by the first and second brake pads;
- and
- an actuating arrangement that selectively moves the brake caliper in an outboard axial direction in relation to the brake carrier;
- wherein the actuating arrangement is electrically operated.
A method of moving a brake caliper of a disc brake assembly in an outboard axial direction in relation to a brake carrier by operating an actuating arrangement, the method comprising the steps of:
- providing the actuating arrangement in which the actuating arrangement has a first portion secured to the brake caliper, and a second portion secured to the brake carrier, and wherein the actuating arrangement is configured to move the first and second portions in relation to one another so as to effect movement of the brake caliper in relation to the brake carrier, the actuating arrangement having an inactive state and an active state, wherein the first and second portions are urged toward a first position by a solenoid and the brake caliper is urged toward a relatively outboard position when in the active state;
- releasing the disc brake assembly from a braking operation;
- and
- moving the actuating arrangement to the active state.
