Abstract
A vehicle brake apparatus comprises brake operation detecting device for detecting an operation of a brake operating member, a fluid pressure type booster which boosts the operating force applied to the brake operating member, a pressure detecting device for detecting a pressure supplied to the fluid pressure type booster, and an electric motor control device. A recirculating type hydraulic pressure modulator is disposed in a hydraulic pressure conduit between a master cylinder and a wheel brake cylinder. The electric motor control device drives an electric motor for activating a recirculating pump in response to the brake operation detected by the brake operation detecting device and the pressure detected by the pressure detecting means so that the pressure in the wheel brake cylinder is modulated.
