A brake fluid pressure retaining unit for retaining brake fluid pressure within a wheel cylinder after releasing a brake pedal is disclosed. The brake fluid pressure retaining unit includes a brake fluid pressure reduction speed control device for retaining reduction speed of the brake fluid pressure within the wheel cylinder less than that of brake pedal load applied by a driver. The brake fluid pressure reduction speed control device may be formed by a restriction in a brake fluid pressure circuit arranged between a master cylinder at which the brake fluid pressure is generated in accordance with a brake pedal load applied by the driver and the wheel.

A primary brake system operated by either one of a hand operated means and a foot operated system is mounted on one of the front and rear wheels, and a secondary brake system operated in response to the operation of the primary brake system is mounted on the other wheel. Consequently, it is possible to provide a braking-force distribution for the front and rear wheels with a predetermined common characteristic, leading to an improved brake feel. A braking-force control is provided for controlling the braking-force distribution to the front and rear wheels in accordance with the operating forces of a first input operated by the hand operated element and a second input operated by the foot operated element, so that an ideal distribution characteristic falls within a region between a first braking-force distribution characteristic for the front and rear wheels by the hand operated element and a second braking-force distribution characteristic for the wheels by the foot operated element, such region being a braking-force distribution characteristic region at a time when the hand and foot operated elements are operated simultaneously.
