ABSTRACT:
In a hydraulic braking pressure control system comprising a brake device (B.sub.FL, B.sub.FR, B.sub.RL, B.sub.RR), hydraulic pressure controller (4) for controlling the hydraulic pressure supply source (2) in accordance with the amount of operation of an operating member (1), an auxiliary hydraulic pressure generator (3) including a working piston (16, 17) operatively connected to the operating member to advance in response to operation of the operating member and being slidably received in a housing (14) with a front surface of the working piston facing a hydraulic pressure chamber (18, 19), a hydraulic pressure transmitter (134) comprising a free piston (132) slidably received in a cylinder body (133) and having opposite ends facing an input hydraulic pressure chamber (130) connected to the hydraulic pressure controller and an output hydraulic pressure chamber (131) leading to the brake device, respectively, and an on-off valve (135) interposed between the hydraulic pressure chamber (18, 19) in the auxiliary hydraulic pressure generator (3) and the brake device and adapted to be closed in response to an increase in output hydraulic pressure from the hydraulic pressure controller, there is further included valve-opening device (136) for forcedly opening the on-off valve in response to the movement of the free piston by a predetermined distance or more in a direction to reduce the volume of the output hydraulic pressure chamber. This ensures that when an abnormality such as wear of a pad or a vapor lock is produced on the side of the brake device in a condition in which the hydraulic pressure supply source is normal, a deficiency of hydraulic pressure can be compensated for, and when a leak of fluid is produced, this can be detected promptly.
