Abstract
A brake system having a master brake cylinder that can be acted upon by fluid pressure of a brake pedal and which communicates with wheel brake cylinders via brake lines, a reversing valve that is closable for traction control and pressure holding and pressure reduction valves for anti-lock control are incorporated into at least one brake line to the wheel brake cylinder. Traction control is effected via a return pump that is connected on the inlet side to at least one brake line. The hydraulic circuit is intended to have a reservoir, which communicates on the inlet side with a self-aspirating return pump via an intermediate line with the brake line via a pressure limiting valve, where the pressure limiting valve has at least one blocking position and an open position on both ends.
