The Girling ‘Twinstop’ Brake 770668

A two-leading shoe air/spring operated wedge brake for heavy commercial vehicles of up to 13 tonnes static axle weight.The dual-wedge design gives a more uniform shoe-to-drum loading pattern than the conventional ‘S’ cam.An auto adjustment mechanism is incorporated which is fully enclosed and functions on the same proven principle as used in automobile rear disc brakes.Overall brake assembly weight is reduced by the use of direct mounted actuators.The brake has been adopted by major vehicle manufacturers in view of higher permissable axle weights, improved half systems and handbrake requirements in Europe.
