Patent attributes
A parking brake actuation system mounted to a tail shaft of a vehicle's transmission is operably connected to a brake assembly of the vehicle having brake pads housed within a brake drum. The parking brake actuation system includes a mounting bracket coupled to the tail shaft of the vehicle's transmission, an actuator coupled to the mounting bracket, and a bell crank coupled to the tail shaft of the vehicle's transmission and the actuator, and also connected to an engagement cam by a linkage assembly. Actuation of the actuator to a retracted position permits rotational movement of the bell crank to transfer through the linkage assembly to engage the pair of brake pads with the brake drum. Actuation of the actuator to an extended position permits rotational movement of the bell crank to transfer through the linkage assembly to disengage the pair of brake pads from the brake drum.
