  • Drum-in-hat brake with reverse scissors actuator
    Patent number: 5529149
    Abstract: The drum-in-hat assembly (10) comprises a disc brake (12) mounted slidably relative to a backing plate (18) which includes an opening (19) through which extends a reverse scissors actuator (40) for the drum brake (30) of the assembly (10). The drum brake (30) includes a pair of arcuate drum brake shoes (32, 34) supported relative to the backing plate (18), with the shoes (32, 34) having a pair of opposed brake shoe ends (36, 38) engaged by the actuator (40). The actuator (40) comprises a pair of levers (42, 46) pivotably attached to one another with each lever (42, 46) having a second lever end (48, 58) engaging a respective end (38, 36) of an associated brake shoe, wherein the second lever end (48, 58) has either a slot (49) or an edge (59) located laterally away from the other and engaging the associated brake shoe end (38, 36). The actuator (40) is free to float relative to the backing plate (18), and the levers (42, 46) are located within a housing (70) attached to the backing plate (18).

  • Heat shield for a brake
    Patent number: 4527672
    Abstract: A heat shield (50) is positioned on a piston (14) in spaced relation to a friction element (16) to prevent heat transfer directly by conduction. The heat shield (50) opposes a boot seal (24) to keep the latter also spaced from the friction element (16).

  • Disc brake assembly
    Patent number: 4436187
    Abstract: A disc brake assembly includes a torque plate (14) with a radial portion (16) and an axial portion (18). The axial portion (18) defines a pair of arms (22,24) with slots (28,32) receiving pin assemblies (36,38). One of the pin assemblies defines a slot (60 or 62) and the torque plate (14) defines a slot (84) to releasably lock a spring (50) in engagement with the pin assembly (36).
