PROBLEM TO BE SOLVED: To provide a vehicle brake device which secures durability for a linear valve to control a servo pressure.SOLUTION: A brake ECU sets a reference servo pressure based on control input of a brake pedal when stopping during stopping of a vehicle, and sets a target servo pressure based on the reference servo pressure during operating the brake. In addition, when a servo pressure calculated according to control input of the brake pedal exceeds a servo pressure change threshold specified with having a prescribed deviation from the reference servo pressure, the brake ECU sets the reference servo pressure based on current control input of the brake pedal.
