Brake installation consisting of a master cylinder associated with a brake booster furnished with a motor driving an actuator piston and acting on the primary piston of the master cylinder by means of a reaction disk against which the piston rests. For a safety operation, the hydraulic actuator connected to the control rod actuated by the brake pedal rests on the rear face of the reaction disk. The actuator piston is combined with an auxiliary piston in order to interact with the reaction disk and it is guided by its sleeve-shaped portion in a bore of the body of the brake booster. An adapting shim is supported by the auxiliary piston in order to receive as a support the end of a rear rod, secured to the primary piston of the master cylinder. The thickness of the assembly formed by the adapting shim and the auxiliary piston is defined on mounting of the master cylinder and of the brake booster as a function of the free travel measured previously.
