PROBLEM TO BE SOLVED: To control wheel cylinder pressure under excellent responsiveness in a brake hydraulic control device suitable as a device to control wheel cylinder pressure of a brake device for an automobile. SOLUTION: A wheel cylinder 22RL is communicated with a master cylinder 16 through a first cut valve 94 and a first pressure intensifying valve 96. A hydraulic passage to communicate the first cut valve 94 and the first pressure booster valve 96 with each other is communicated with a reservoir 54 through a first linear 4D-1 . A brake fluid is stored in the reservoir 54 under normal pressure. The first cut valve 94 is closed, and the first pressure intensifying valve 96 is opened, and wheel cylinder pressure of a wheel cylinder 22FL is controlled so as to be reduced by linearly controlling the first linear 4D-1 . |
