Claim:
1. A brake system, comprising: a brake pedal; a master cylinder configured for generating hydraulic pressure in response to pressing of the brake pedal; a plurality of wheel brakes comprising a first wheel brake installed in a first wheel and a second wheel brake installed in a second wheel; at least one hydraulic line interconnecting among the master cylinder, the first wheel brake and the second wheel brake; a plurality of valves installed in the at least one hydraulic line and configured to connect or disconnect fluid communication among the master cylinder, the first wheel brake and the second wheel brake via the hydraulic line; and a controller configured to control operation of, the plurality of wheel brakes and the plurality of valves for braking in a normal operation mode and an abnormal operation mode, the first wheel brake comprising a mechanical-hydraulic combination brake configured to generate braking force by mechanical operation for braking the first wheel and further configured to operate using hydraulic pressure transferred thereto via the hydraulic line, wherein the mechanical-hydraulic combination brake is further configured to generate hydraulic pressure for applying to the second wheel brake via the at least one hydraulic line when generating the braking force by mechanical operation; the second wheel brake configured to, operate using the hydraulic pressure applied thereto via the hydraulic line; wherein in the normal operation mode, the master cylinder is disconnected from the first and second wheel brakes and further the first and second wheel brakes are connected via the at least one hydraulic line such that the hydraulic pressure generated by the first wheel brake is transferred to the second wheel brake for operating the second wheel, brake independent of the hydraulic pressure in the master cylinder, wherein in the abnormal operation mode, the master cylinder is connected to the first and second wheel brakes such that the hydraulic pressure in the master cylinder is transferred to each of the first and second wheel brakes for braking each of the first and second wheels.
