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.

Abstract: A vehicle braking system in which an annular piston brake and a booster to generate an amplified output force for actuating the brake are combined to form an integrated unit. The booster is mounted on an axle casing in which the piston brake is located so that the amplified force acts directly on fluid in a chamber to displace the piston brake. A self-bleeding facility for the brake fluid is provided via the booster.

Abstract: A dual hydraulic booster assembly for a braking system of a tractor or like vehicle has a logic valve operable in a first mode to control the supply of pressure fluid for braking on one side of the vehicle to facilitate steering, and in a second mode of operation to control the supply of fluid pressure for braking on both sides of the vehicle for full vehicle retardation. A pressure amplifier valve may be provided to increase the pressure of the pressure fluid from the logic valve for braking in the second mode of operation. The logic valve and amplifier valve may be incorporated into the booster assembly to provide an integrated unit.
