ABSTRACT:
An assisted braking device comprises a master cylinder and piston assembly the piston of which is connected to the piston of an assisting jack by an axially aligned interconnecting element. A brake pedal is adapted to operate the interconnecting element by a thrust member and a lever which is articulated to the interconnecting element and connected at one end to the thrust member; the other end of the lever acts on a distributor which can direct hydraulic fluid under pressure to the existing jack. A force on the brake pedal is transmitted via the thrust member and the lever to the interconnecting element to displace the master piston, and the end of the lever acting on the distributor simultaneously energizes the assisting jack. Safety abutment means which operate in the event of failure of the assisting hydraulic pressure allow displacement of the master piston by the force directly applied through the thrust member.
