PROBLEM TO BE SOLVED: To provide a brake controller configured to prevent a reduction in stiffness feeling of a brake pedal even when an actuator of a booster enters a full-load state.SOLUTION: A brake controller 1 includes: a wheel cylinder pressure control mechanism 3 provided between a master cylinder 2 and each of wheel cylinders 4a-4d to supply operating fluid of the master cylinder 2 to the wheel cylinders 4a-4d; and pressure-increasing valves 12, 13, 22, 23 provided in the wheel cylinder pressure control mechanism 3 to adjust flow resistance of the wheel cylinder pressure control mechanism 3. A wheel cylinder pressure control device 9 determines whether the a full-load state has been entered where even if an output of a drive motor 50 is maximized, thrust of a primary piston 2b and reaction of liquid pressure in the master cylinder 2 are balanced with each other to stop the primary piston 2b. When the full-load state is determined, opening degrees of the pressure-increasing valves 12, 13, 22, 23 are reduced to increase flow resistance of the wheel cylinder pressure control mechanism 3. |
