PROBLEM TO BE SOLVED: To inhibit the vibration of an intensification control valve and a decompression control valve in a brake fluid pressure controller. SOLUTION: In the case when the operation of an accelerator pedal is released in a non-operating condition of a brake pedal, the fluid pressure of a brake cylinder is intensified and held to a degree to keep a frictional engagement member at a position near a brake rotating body. Whereby, a clearance between a brake pad and the brake rotating body is reduced. When the brake pedal is actually pressed, the fluid pressure of the brake cylinder is controlled to the pressure in accordance with a brake operating condition by controlling a pressure intensifying linear valve. Here as the clearance is reduced, a flow rate and the amount of the operating fluid flowing in the intensification linear valve can be reduced, and the vibration can be inhibited.
