Abstract
In a brake system, two first fluid pressure chambers of a master cylinder respectively communicate with two second fluid pressure chambers of a motor cylinder. The two second chambers communicate with four wheel cylinders through an ABS. The wheel cylinders are operated by brake fluid pressure generated by the master cylinder in an abnormal situation where the motor cylinder is non-operational. The brake system includes two separate independent fluid pressure lines: one line extending from one of the first chambers in the master cylinder to the wheel cylinders via one of the second chambers in the motor cylinder; and the other line extending from the other first chamber in the master cylinder to the wheel cylinders via the other second chamber in the motor cylinder. Thus, even if an abnormality occurs in one of the two fluid pressure lines, a minimum necessary braking force is secured.
