Abstract
The present invention relates to a brake corrector subject to the load of a vehicle despite the possible variation in the height of the seating of the latter. According to the invention, the corrector comprises a fluidic pressure sensor arranged between the vehicle chassis and the corresponding end of a suspension spring of the vehicle, a body (1) in which a slidably mounted at least one piston (2, 3) controlled by an actuating rod (10) and arranged so as to interact with a valve element in order to control a passage of the corrector, the body and the fluidic sensor being connected fluidically in such a way that a variation in pressure determines a first force exerted on the piston, and a sensor of the height of seating of the vehicle, the response of which determines a second force likewise exerted on the piston, the first and second forces combining to act on the piston (2, 3).
