In the provided improved braking system, if an electrical system malfunctions, the hydraulic pressure in a master cylinder (62) activates a pressure-increasing mechanism (100). A servo pressure is supplied to brake cylinders (42FL and 52RR) for a front left wheel (2) and a rear right wheel (48), and hydraulic pressure is supplied from the master cylinder (62) to a brake cylinder (42FR) for the front right wheel (4). This reduces the yaw moment, working to prevent situations in which there is not enough braking force. If there is a possibility of fluid leakage, hydraulic pressure from a powered hydraulic pressure source (64) is supplied in a controlled manner to the brake cylinders (52) for the left and right rear wheels (46 and 48), and hydraulic pressure is supplied from the master cylinder (62) to the brake cylinders (42) for the left and right front wheels (2 and 4). The brake cylinders (42FL and FR) for the left and right front wheels (2 and 4) are cut off, and cut off from the brake cylinders (52) for the left and right rear wheels. The provided braking system thus can cut off the three systems from each other, preventing fluid leakage from affecting other systems. |
