Abstract
A parking brake for a wheel rotor having a brake pad associated therewith includes a housing defining first and second passages. First and second pistons are provided in the respective first and second passages. Spindles extend into and are connected with each piston. A clutch unit is connected to the spindles and includes a motor. The clutch unit has a first condition allowing for rotation of the spindles in response to hydraulic pressure applied to the pistons such that the pistons are axially movable within the passages and relative to the spindles into engagement with the brake pad. The clutch unit has a second condition for rotating the spindles to drive the pistons into the brake pad and apply the parking brake.
