  • Publication number: 20110100772
    Abstract: The present invention is premised upon a clip and housing plate assembly capable of (“to accommodate”) loading, unloading and retaining a cable end within the housing plate assembly. Of particular interest is the clip and housing plate assembly used in a drum brake assembly and where the cable end is part of a cable assembly for a parking brake. The clip and housing plate assembly having clip member and a housing plate member and wherein the clip member is generally disposed outside an outer surface (or inside an inside surface) of the of the housing plate member and rotatably connected thereto.

  • Publication number: 20090101456
    Abstract: A corner module, comprising a knuckle, a hub and bearing a caliper assembly including a caliper that carries at least two opposing and spread apart brake pad assemblies, and a rotor having a rotational axis including a hat portion and a disc portion, the disc portion disposed between the at least two brake pads. At least one of the brake pad assemblies and the rotor includes a main body portion having a first stiffness and at least one sacrificial portion having a second stiffness that is less stiff than the first stiffness of the main body portion. In a brake-off position, a first running clearance between the brake pad assembly and the rotor of the at least one sacrificial portion will be lower than a second running clearance between the friction pad and the rotor of the main body portion. In a brake-on position, the axial deflection of the at least one sacrificial portion exceeds the axial deflection of the main body portion.

  • Patent number: 7467693
    Abstract: A disc brake return spring comprises a V-shaped spring having two spring members, with each member ending in an engagement leg. Each engagement leg is angled with respect to the spring legs in a fashion so that the spring applies a moment to the friction pad to counteract rotation that occurs about the backing plate supports. The return spring is employed in a disc brake assembly having friction pads with backing plates that are disposed on either side of a rotor for braking purposes.

  • Patent number: 4666022
    Abstract: A wedge-type actuator for a drum type brake including a positive stop for limiting the degree of relative movement between the cage and the wedge for avoiding push through. The stop is operative between the cage and a member other than the wedge for limiting the forces exerted on the unit during its operation.

  • Patent number: 4175795
    Abstract: In a fluid-pressure operated anti-skid braking system operation of a brake-applying relay valve is controlled by control pressure in an application chamber. A memory chamber is connected to the application chamber through a one-way valve and an orifice permits pressure in the memory chamber to decay into the application chamber when the pressure in the application chamber reduces. Re-application of the brakes following a skid is controlled by closure of a latch valve which permits only a restricted flow of control pressure into the application chamber. This is sufficient to re-apply the brakes rapidly in a first stage until the pressure in the application chamber becomes equal to that of the decayed pressure in the memory chamber, whereafter brake re-application continues at a slower rate since the restricted flow of control pressure has also to increase the pressure in the memory chamber.
