A hydraulic balanced braking system, comprising two oil pressure cylinders, two hydraulic brakes, and an oil-pressure balance unit. The two oil pressure cylinders are mounted close to braking handles. The oil-pressure balance unit is inserted between the two oil pressure cylinders and the two hydraulic brakes and further comprises two parallelly oriented oil cylinders, two primary pistons, two secondary pistons, and a connecting plate. Two inlets at upper sides of the two oil cylinders are connected with the two oil pressure cylinders, respectively, transmitting oil pressure from the two oil pressure cylinders to the two primary pistons. The two secondary pistons are mounted below and driven downward by the two primary pistons, respectively, thus generating oil pressure and via two outlets driving a braking movement of the two hydraulic brakes. The connecting plate is fastened to upper ends of the two secondary pistons, so that upon a downward movement of one of the primary pistons both of the secondary pistons are driven downward, simultaneously generating oil pressure in both of the hydraulic brakes.
