  • Patent number: 7410034
    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.

  • Patent number: 6651789
    Abstract: A drum-in-hat park brake assembly for a vehicle wherein first and second brake shoes are retained and aligned on a backing plate by first and second pins. The first and second shoes are moved into engagement with a drum by a force applied to an actuator by a cable assembly. The backing plate is characterized by a flange having a slot therein and the cable assembly is characterized by a cable with a fitting on a first end that has a stem with an annular rib thereon. The stem passes is passed through the slot while the annular rib engages the flange to limit the movement of the first end of the cable toward the actuator and to limit the movement of the first end toward the actuator mechanism to prevent the lever from being axially moved past a position of rest and change the radial alignment between the first and second brake shoes and the backing plate by the action of a release spring.

  • Patent number: 6234278
    Abstract: An anchor plate for a brake assembly and a method of attachment to an annular rib of axle tube of a vehicle. The anchor plate which defines a backing plate for a drum brake and guide rails for a caliper of a disc brake has a flange with a keyhole having with an arcuate length approximately equal to an axle retained in the axle tube. In assembly, the anchor plate is moved in an angled plane toward the axle until the keyhole moves past the axle. The anchor plate is rotated into radial alignment with axis of the axle and the flange is aligned with the axle tube. Then the flange is axially moved onto the axle tube until the flange engages the annular rib. Bolts are located in holes in the flange to fix the anchor plate to the axle tube. Thereafter, a bracket is attached to the anchor plate to position a cantilever member which retains a cable sheath is aligned with a lever opening in the anchor plate.
