Abstract
The invention provides an assisted braking device which operates in conjunction with a brake pedal disposed at one end of a brake lever. The device comprises a master piston and cylinder assembly the piston of which is interconnected with the piston of an assisting jack by means of a connecting element on which is articulated the brake lever. The end of the brake lever remote from the brake pedal acts on a distributor adapted to feed the assisting jack with assisting hydraulic pressure so that when a force is applied to the brake pedal and thereby to the master piston via the connecting element, the distributor directs hydraulic fluid under pressure to the assisting jack, the piston of which then applies an assisting force to the connecting element.
