Abstract: A braking system for a vehicle including front and rear wheels having wheel brakes includes a fluid displacement mechanism for supplying brake fluid to at least one of the wheel brakes. The fluid displacement mechanism includes a piston having a first position prior to braking and a second position for applying braking. A fluid accumulator is in fluid communication with the fluid displacement mechanism and stores brake fluid. A valve is in fluid communication with the fluid displacement mechanism and the accumulator and is configured to be closed while the piston moves from the second position towards the first position to prevent depletion of the accumulator.
