PURPOSE: A vehicle brake drag reducing device is provided to prevent the abnormal abrasion of a disc and a brake pad by reducing brake drag phenomenon. CONSTITUTION: A vehicle brake drag reducing device comprises a hydraulic line(40), an inlet valve(50), an outlet valve(60), and an accumulator(70). A hydraulic line is mutually connected to supply fluid pressure to a caliper(30) from a master cylinder(20) according to the manipulation of a brake pedal(10). The inlet valve and the outlet valve are connected on the hydraulic line around the caliper to open and close the hydraulic line. The inlet valve and outlet valve supply the fluid pressure to the caliper from the master cylinder through the opening and closing of the hydraulic line The inlet valve and outlet valve stop supply to make the fluid pressure, supplied to the caliper, slip out. The caliper has a disc inside. The brake pad is arranged in both ends of the disc across the disc. The accumulator is installed on the fluid pressure connected between the master cylinder and the inlet valve in order to accumulate the fluid pressure supplied from the outlet valve. |
