Abstract
A vehicle wheel spring brake actuator has a service braking piston and cylinder assembly and an auxiliary parking or emergency braking piston and cylinder assembly, the emergency braking piston being spring biassed towards a brake-applying position and normally held off by an opposing fluid pressure, upon release of which the spring force is transferred through the emergency braking piston and a force transferring member to the service braking piston to apply the brake. A quick release device is movable through a small distance to permit relative movement between the force transferring member to release the applied brake, the release device and the force transferring member extending through the emergency braking piston freely and with clearance.
