ABSTRACT:
The disc brake (10) includes a parking cartridge device (28) which transfers reaction forces of the mechanical parking actuator (36) directly to the caliper housing (12) and also provides support and guidance for a cable (90) attached to lever arms (70) of the mechanical parking actuator (36). The mechanical parking actuator (36) is disposed within an opening (34) of the parking cartridge housing (30), the parking cartridge housing (30) having a plurality of through openings (42) so that bolts (50) may be secured at one end to the caliper housing (12) and at the other end to a bracket (60) which abuts an end (33) of the parking cartridge housing (30). An end plug (48) encloses the opening (34) and abuts the bracket (60) so that reaction forces from the mechanical parking actuator (36) are transmitted directly to the bracket (60), bolts (50), and caliper housing (12), and the parking cartridge housing (30) does not receive any reaction forces so that it may be made of a lighter weight material and of a smaller construction. The mechanical parking actuator (36) includes a pair of lever arms (70) which are clasped together by a U-shaped retainer (80) or pin (100) which secure the cable (90) to the lever arms (70).
