Abstract
A brake fluid pressure retaining unit for a vehicle comprises a solenoid valve SV arranged in a brake fluid passage FP between a master cylinder MC and a wheel cylinder WC so as to shut off or communicate the brake fluid passage FP. In the case that a transmission of the vehicle is shifted to a driving position, the solenoid valve SV is switched to a shut-off position when the vehicle stops with a brake pedal BP depressed. The solenoid valve SV is switched to a communicating position when driving force is exerted on the vehicle. Brake fluid pressure is retained within the wheel cylinder WC when the solenoid valve SV is in the shut-off position. The brake fluid pressure within the wheel cylinder is retained after releasing the brake pedal so that braking force continues to act on the vehicle. The brake fluid pressure retaining unit comprises control means CU such that when the solenoid valve is in the shut-off position and the transmission is shifted to a non-driving position, the solenoid valve SV is returned to the communicating position on condition that depression of the brake pedal BP is released.
