Abstract
A braking force retaining unit has a cut-off valve and a control unit. The cut-off valve retains predetermined brake hydraulic pressure at the wheel cylinders until a predetermined releasing condition is established, even after the depression of a brake pedal is released when a vehicle is stopped. When the predetermined releasing condition is established, the retained brake hydraulic pressure is released, when the depression of the brake pedal is released, the control unit controls the cut-off valve so as to retain the brake hydraulic pressure while reducing the retained brake hydraulic pressure at a first reduction rate. When the predetermined releasing condition is established, the control unit controls the cut-off valve so as to allow the retained brake hydraulic pressure to be reduced at a second reduction rate which is faster than the first reduction rate.
