PURPOSE:To reduce the number of control devices, by installing each of antilock brake control devices separately in position between a channel branch point of two sytems of cross piping and a master cylinder side by side, while operating each control device when at least one side of front and rear wheels of the corresponding system is locked. CONSTITUTION:In case of an A system on one side of two systems of cross piping, a hydraulic control unit 4A is installed in position between a master cylinder 2 and a branch point of branch channels 5AF and 5AR leading to front and rear wheels. In addition, a P valve 7A is installed in the branch channel 5AR leading to rear wheels. And, the hydraulic control unit 4A is operated when at least one side of a left front wheel 6AF and a right rear wheel 8AR is locked by each signal out of speed sensors 9AF and 9AR of these wheels 6AF and 8AR whereby braking hydraulic pressure in the A system is controlled. And, even in a B system on the other side, a hydraulic control unit 4B, a P valve 7B and speed sensors 9BF and 9BR are installed as in the A system, and control takes place likewise. |
