Abstract
The invention relates to an anti-skid apparatus operatively positioned between a master brake cylinder and wheel brakes of a vehicle brake system. The anti-skid apparatus protects the wheel brakes from locking. The apparatus includes a controllable master brake line valve, which is open in its basic position and during normal braking; only in anti-skid braking operation does it disconnect the outlet of the return pump from the master brake cylinder.
