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.

A braking control system of a vehicle includes a pressure control device that regulates brake fluid flow to a brake caliper of a wheel from a brake fluid cylinder. A pressure sensor measures a pressure of the brake fluid applied to the brake caliper. A filter module filters the measured pressure based on a rotational frequency of the wheel. The filtering produces a filtered pressure of the brake fluid applied to the brake caliper. A target pressure module sets a target pressure for the brake fluid for application to the brake caliper. A difference module determines a pressure difference between the filtered pressure and the target pressure. A pressure control module actuates the pressure control device based on the pressure difference.
