Abstract
Variable-ratio braking corrector for a vehicle, comprising a housing provided with at least two parallel bores (14, 16), at least two pistons (24, 26) one mounted slideably in each bore, the two pistons projecting from the housing and cooperating with the two ends of a rocker (28) mounted in an articulated manner relative to the housing (12), the hinge pin (48) of the rocker (28) being displaceable by means of a mechanism connected to the vehicle suspension, to vary the ratio of the corrector as a function of the vehicle load, characterized in that the corrector also comprises a reversible escape device (50) in the mechanism, comprising at least two elements (52, 58) coupled pivotably to one another, one (58) being coupled to the hinge pin (48) and the other (52) being stressed toward a rest position by a spring mechanism (60).
