Abstract
A parking brake system for a vehicle includes an at least partially bistable valve unit to generate a control pressure for controlling at least one function of the parking brake system, and a relay valve which receives the control pressure from the valve unit and either pressurizes or bleeds at least one spring-loaded cylinder according to the control pressure. The valve unit is integrated into a first module integrated into a compressed air supply unit, and the relay valve is arranged in a second module which is arranged at a distance from the first module and the compressed air production system.
