A vehicle brake circuit comprising a brake actuator (14), a first manually operable valve (6), a second electrically operable valve (4) and a fluid reservoir (16) for the supply of fluid to the actuator. The first valve is connected to the fluid reservoir both directly and via the second valve and the first valve is biased in a position such that a direct fluid connection between the fluid reservoir and the first valve is blocked and a unblocked fluid connection between the fluid reservoir and the first valve is via the second valve. Movement of the second valve controls activation or deactivation of the actuator and movement of the first valve out of the biased position overrides control of the actuator by the second valve.
