PURPOSE: A brake of a vehicle is provided to promptly perform air bleeding by making a fluid flow toward a wheel cylinder and blocking up the counterflow of the fluid. CONSTITUTION: A brake of a vehicle comprises a plate(2) having many passage holes(1) and fixed in a hydraulic cylinder(57), a valve plate(3) to open and close the passage holes by spacing apart from the plate or contacting to the plate, and an elastic member(4). If a brake pedal is stepped on continuously, the fluid and air in a hydraulic pipe flow toward a wheel cylinder. Then, the air in the wheel cylinder is discharged through an air bleeding valve. If the brake pedal is released, the passage holes are closed, the and counterflow of the fluid and air is blocked up. Therefore, air bleeding work is accomplished easily.
