ABSTRACT:
A brake fluid pressure control apparatus that can switch from brake fluid pressure control to normal brake operation immediately after the brake fluid pressure control terminates. This apparatus has a master cylinder, pressure control valves for controlling the brake fluid pressure in wheel cylinders and a pump for pumping out the brake fluid to the wheel cylinders. It also has an accumulation chamber connected to an inlet of the pump which accumulates the brake fluid in an airtight condition to generate negative pressure. Further, it has a cut-off valve for cutting off the flow of the brake fluid from the master cylinder to wheel cylinders and a return conduit connected between the wheel cylinders and the accumulation chamber.
