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 are threadably connected with each piston. An electromagnetic locking mechanism provided between the spindles having a first magnetic polarity for placing the locking mechanism in a first condition allowing relative rotation between the spindles and the pistons such that the pistons are axially movable within the passages and into engagement with the brake pad in response to hydraulic pressure applied to the pistons. The electromagnetic locking mechanism has a second magnetic polarity for placing the locking mechanism in a second condition preventing relative rotation between the spindles and the pistons such that the pistons remain engaged with the brake pad when hydraulic fluid pressure is removed from the pistons.
