Abstract
A pressure reduction mechanism (10) is installed in a brake circuit of the rear axle of a motor vehicle, comprising a master cylinder (1) and at least one monitoring device, the mechanism executing the brake-pressure reduction only in specific circumstances and comprising a regulating piston (14) sliding sealingly in a bore (13) and stressed by at least one spring (16, 17) in the opening direction of a regulating valve (15). The spring (16, 17) is arranged in a sealed chamber filled with an incompressible fluid, and a solenoid valve (22) controls the opening or closing of communication between the chamber and a reservoir of the fluid under low pressure.
