An anti-skid braking system incorporates a modulator assembly through which fluid from a source is supplied to a brake. The modulator assembly comprises a de-boost piston working in a bore in a housing, an expander chamber connected to the brake and defined in the bore between one end of the piston and a first valve, and a second valve for controlling the application to the piston of support fluid to determine the relative position of the piston in the bore, the second valve being manipulated in response to a skid signal. The first valve is normally biassed in to a fully open position, and the operation of the first valve is controlled independently of the piston. An inhibit device is incorporated to ensure that at the termination of a skid signal first valve is maintained in a closed position at least until the piston has returned to an advanced position in which the effective volume of the expander chamber is at a minimum value.
