PURPOSE: A hydraulic pressure control valve of a brake is provided to conveniently install an isolating member by improving structure of the isolating member combined to a leakage passage and to sense breakage of a valve by discharging fluid in damage of the valve. CONSTITUTION: A hydraulic pressure control valve in a brake comprises first second cylinder units(11,12) formed in a valve body(10); first and second pistons(13,14) separately mounted on the cylinder units; a first inlet port(15) compressing the first piston by letting brake fluid into a front wheel from a master cylinder; a second inlet port(16) installed on the second cylinder unit by penetrating the first cylinder unit to let the brake fluid into a rear wheel; an output port(17) supplying the brake fluid into the rear wheel through the second cylinder unit; an interlocking passage(18) connecting the first cylinder unit and the output port; a socket(19) supporting the first piston by being mounted on an entrance of the first cylinder; sealing members(20,21) formed on an outer side of the first piston; and a packing(22) closing or opening the interlocking passage by movement of the first piston.
