A braking system in a vehicle comprises a dynamometer for sensing force Fp applied to brake pedal 1, a braking force amplifier 3, a master cylinder 4, a sensor 5 for sensing pressure Pv, a regulating unit 7 which includes a pump and valves, an ECU 6, and a manometer 8 which senses pressure Pr at wheel brakes 9, 10. The pump is actuated automatically to increase pressure Pr, if (i) the ratio Fp/Pv does not lie within a set range (e.g.because of a fault in the amplifier) and (ii) Pr is not sufficient.
