Abstract
Upon occurrence of a change in the load versus fluid loss property, the braking force for the given brake pedal operation amount is changed so that the vehicle operator is enabled to perceive the change in the load versus fluid loss property. In a vehicle brake system comprising a motor actuated cylinder, wheel cylinders, a stroke sensor for detecting a brake pedal operation amount, a target value setting circuit for setting a target stoke of the motor actuated cylinder, and a fluid pressure compensating circuit for correcting the target stoke upon detection of a deviation between a brake fluid pressure reference value corresponding to the brake pedal operation amount and an actual brake fluid pressure in a direction to reduce the deviation, a stroke limiting circuit restricts a compensation value produced by the fluid pressure compensation circuit according to the brake pedal operation amount.
