ABSTRACT:
A brake noise reduction system (84) which is particularly adapted for use with the hydrostatic transmissions of vehicles such as skid-steer loaders, includes a fixed caliper assembly (86) and multiple brake disc assemblies (66) that are individually connected to the transmission. The caliper assembly (86) includes a bore (96) guiding the brake pucks (98) into selective engagement with the brake disc assemblies (84) responsive to a manual cam actuation. Each brake disc assembly (66) includes a resilient damper ring (152) secured between a retainer plate (154) and a disc plate (150) to reduce rattling of the assembly and help to reduce overall noise of the hydrostatic tranmission. The brake pucks (98) are actuated by a manual lever (132) connected to a rotatable cam (112) associated with an axial plunger (120). The cam (112) is rotatable about an axis parallel to the bore (96) in the caliper assembly (86) containing the brake pucks (98) and plunger (120) to provide a wider range of motion in a more compact space.
