Abstract
A parking brake system for a motor vehicle transmission is provided. The parking, brake system includes a brake cylinder having a brake piston movable between braking and locking positions, a piston lock provided to lock the brake piston in the locking position, a piston valve configured to activate the brake cylinder using a fluid, and a locking valve configured to activate the piston lock using a fluid. The piston valve can be connected, in a fluid-conducting manner on the downstream side facing away from the brake cylinder, to a supply pressure system, and the locking valve, on the side facing away from and downstream of the piston lock, can be connected in a fluid-conducting manner to the supply pressure system, such that the locking valve is arranged downstream of and parallel to the piston valve relative to the supply pressure system.
