ABSTRACT:
The boosted brake system comprises two tandem master cylinders (15, 16), each controlled by way of the piston of a vacuum booster (10, 11) comprising at least two chambers, one (10) of these brake boosters being controlled by way of a pedal and comprising a valve mechanism making it possible to generate a difference between the pressures prevailing in the two corresponding chambers, and a reservoir (17) for feeding brake fluid to the associated hydraulic circuits the two chambers of one (10) of these boosters communicate respectively with the two corresponding chambers of the other booster (11), and the two hydraulic circuits (30, 32) associated with one (15) of the master cylinders communicate respectively with the two hydraulic circuits (30, 32) of the other master cylinder (16).
