Abstract
A brake control system for preventing a rear-wheel lock in an automotive vehicle comprises a fluid pressure control valve controlling a brake fluid pressure distribution between front and rear wheels such that a rear wheel-cylinder brake fluid pressure is kept substantially constant in a range above a critical fluid pressure at which the brake fluid pressure distribution is essentially varied, a longitudinal acceleration sensor for monitoring a deceleration of the vehicle body, and a set of reversible motor and return spring for increasing the critical fluid pressure in accordance with an increase in the deceleration of the vehicle body only when the deceleration is increased.
