Abstract
An assisted braking device comprises a master cylinder and piston for applying the brakes. Depression of a brake pedal is arranged to move the master piston and to control brake assisting means to assist in the movement of the master piston. The assisted braking device is arranged such that if the brake assisting means is defective a driver can still effectively displace the master piston by applying the brake pedal. In this respect a safety rod is connected between a pedal lever of the brake pedal and the master piston independently of the brake assisting means and is arranged to be actuated if the assisting means break down.
