PURPOSE: A disk brake for a vehicle is provided to prevent the loss of the braking power by making the fluid pressure of leading side cylinder smaller than the fluid pressure of the trailing side cylinder. CONSTITUTION: A disk brake for a vehicle comprises a disc(60), a pad(70), a caliper housing(10) and a plurality of pistons(52). The disc revolves with wheels. The pad is located between the both sides of the disc and presses the disc. The caliper housing is installed in one side of the car body. A plurality of cylinders is formed inside the caliper housing. A plurality of pistons is respectively inserted into a plurality of cylinders. The piston compresses the pad in the disc direction using the fluid pressure within the cylinder. The fluid pressure within the leading side cylinder is smaller the fluid pressure within a trailing side cylinder based on a disc rotation direction.
