A relief valve of a brake system is provided to improve quality and reliability of the product by maintaining normal pressure using a simplified structure, coping with high pressure or abnormal pressure that may be generated during operation of the brake system. A relief valve of a brake system comprises a block(10), a filter(20), and a holder(30). The block includes an inlet(12) connected with a path of the brake system, a hollow part(14) fluidly communicated with the inlet in an axial direction, and an outlet(16) fluidly communicated with the hollow part to discharge hydraulic oil. The filter is inserted in an upper part of the hollow part and has an oil path(26) fluidly communicated with the inlet of the block. The holder is inserted to a lower part of the hollow part of the block, and has a receive part(32) along the central axis. In the receive part, a plunger(36) is resiliently supported by a spring(34) to selectively open and close the oil path of the filter. In addition, a hole(38) is formed in the holder in fluid communication with the outlet of the block. |
