ABSTRACT:
To improve the reliability of operation of an anti-skid braking system, and to provide a warning indication if malfunction should occur in such a system (ABS), a pressure-responsive switch (6, 62, 63) having two switching elements (S.sub.1 S.sub.2 ; 43a, 44a, 43b, 44b, 46a, 46b, 47a, 47b) is connected to a pressurized hydraulic brake fluid connection line to a control valve for a vehicle brake, the switches providing, respectively, control signals of different levels of pressure applied thereto, and, in case of failure of one switch to respond to a higher pressure level, at which time a pump motor is to be energized to resupply the pressure, a second switch, responsive to a lower pressure value, is provided, providing a further warning indication and, if appropriate, disconnecting the ABS with a disconnect indication to the operator that the braking system is placed back under operator control.
