Title: Anti-skid braking system for vehicles

Abstract: An anti-skid braking system for vehicles includes a connection between a master cylinder and each wheel brake by-passing a modulator for modulating the braking pressure in the event of a skid. Each by-pass connection is controlled by a valve and all the by-pass valves are normally maintained closed by a single piston responsive to the same fluid pressure which operates the modulator. The system may also include valves for isolating the modulator from the wheel brakes when the by-pass valves open.
