A power assisted brake system for a vehicle equipped with an antiskid system. The brake system includes a driver actuated control valve to switch on the assist power and a safety device which enables a certain braking power in case of failure of the assist power. The antiskid hydraulic control valves control the pressure in the hydraulic assist power connection. The safety device includes a hydraulic emergency connection completely separate from the hydraulic assist power connection. This hydraulic emergency connection enables the elimination of the strong emergency spring employed in prior art arrangements. Two embodiments are disclosed.
