ABSTRACT:
A parking brake including a disc fixed to a vehicle and a plurality of clips attached to the disc to align channels on first and second brake shoes with a braking surface on a drum. Each clip has a rectangular shape with a flat first end fixed to the disc and a U-shaped second end defined by parallel first and second sides separated by a spacer. A projection on the first end is mated with the disc to align the second end along a radial plane of the axis of the drum. The sides of the second end resiliently engage the channels and align friction surfaces on the first and second brake shoes with the braking surface. In addition, the clips attenuate any vibration that may occur between first and second brake shoes and the drum during movement of the vehicle to reducing the creation of noise in the brake.
