A hydraulic control system of a continuously variable transmission for a vehicle reduces cost and improves quality reliability by adding switch valve function to a manual valve. The hydraulic control system may control a first brake operated at a first forward speed, a first clutch operated at a second forward speed, and a second brake operated at a reverse speed. The first clutch and the second brake may be operated by operation pressure controlled by a first proportional control solenoid valve and supplied through a manual valve, and the first brake may be operated by operation pressure controlled by a second proportional control solenoid valve, wherein the second proportional control solenoid valve controls hydraulic pressure received from the manual valve to be supplied to the first brake as the operation pressure.
