Claim Text:
1. A brake system for a vehicle, comprising: a brake pedal; a master cylinder configured to generate hydraulic pressure in response to pressing of the brake pedal; a plurality of wheel brakes comprising a first wheel brake, a second wheel brake, a third wheel brake and a fourth wheel brake; a first electric booster configured to generate hydraulic pressure in response to pressing of the brake pedal; a second electric booster configured to generate hydraulic pressure in response to pressing of the brake pedal; the first wheel brake in fluid communication with the first electric booster and further in fluid communication with the master cylinder via a first valve; the second wheel brake in fluid communication with the second electric booster and further in fluid communication with the master cylinder via a second valve; wherein if the first and second electric boosters are in normal operation, the system is configured to disconnect the fluid communication between the master cylinder and the first wheel brake and also to disconnect the fluid communication between the master cylinder and the second wheel brake such that the first wheel brake operated by hydraulic pressure from the first electric booster is fluidly disconnected from the second wheel brake operated by hydraulic pressure from the second electric booster, wherein if both the first and second electric boosters are not in normal operation, the system is configured to connect the fluid communication between the master cylinder and the first wheel brake and also to connect the fluid communication between the master cylinder and the second wheel brake such that the first wheel brake and the second wheel brake are commonly operated by hydraulic pressure from the master cylinder.
