Abstract
A parking braking system for a vehicle uses an electronic braking system (EBS) as a primary source for generating a parking brake force via pneumatic brake actuators. Each pneumatic actuator actuates a piston that is adapted to rotate a pivoted lever, which moves to apply brake pads against a brake disc. The parking braking system includes a hand control that controls actuation of the pneumatic brake actuators. Vehicle brakes for non-parking braking purposes are controlled by electronic signals generated in response to a driver's foot-generated braking demand. An electronic controller is adapted to control a supply of pressurized air to the pneumatic brake actuators in accordance with the driver's braking demand. When parking braking is selected by actuation of the hand control, the vehicle brakes are applied and mechanically locked into place with a stop device that engages the pivoted lever to hold the respective vehicle brake in a parking braking condition, irrespective of whether a brake force generated by the EBS is subsequently reduced.
