ABSTRACT:
A disc brake caliper assembly for use with a disc rotor includes first and second opposed pads positionable on opposite sides of the disc rotor and movable towards and away from one another to apply a braking force to the disc rotor during braking operation, and a stationary member which receives a braking torque from the pads during the braking operation. A single pad-supporting pin has opposite ends that are supported by the stationary member, and the single pad-supporting pin is adapted to support the pads in the radial direction. The pad-supporting pin is located at a position offset from the center of each of the first and second pads. A one-piece spring member is supported on the stationary member. The one-piece spring member includes a first spring portion for applying a biasing force to the first pad having an axially directed component for biasing the first pad axially outwardly away from the second pad when the braking operation ceases and a radially directed component for biasing the first pad radially inwardly to prevent the first pad from rattling. The one-piece spring member also includes a second spring portion for applying a biasing force to the second pad having an axially directed component for biasing the first pad axially outwardly away from the first pad when the braking operation ceases and a radially directed component for biasing the second pad radially inwardly to prevent the second pad from rattling.
