Abstract
An hydraulic brake pressure control device includes an inertia-controlled valve adapted to control the braking pressure applied to rear wheel brake cylinders from a master cylinder in accordance with the rate of deceleration of the vehicle. In the control device, a bypass passage is provided to facilitate air-purge from the inertia-controlled valve assembly during charge of brake fluid to the braking system, and a check valve is arranged to open and close the bypass passage in such a manner that braking force distribution ratio between the front and rear wheel brake cylinders can be accorded with an ideal distribution ratio characteristic curve.
