PROBLEM TO BE SOLVED: To restrain a shortage of braking force by excessive pressure reduction at antiskid control time in low speed travel. SOLUTION: In antiskid control, either of a pressure reducing mode and a holding mode is determined according to a control map on the basis of a wheel speed (S7), and when set in a pulse pressure increasing mode (S11), pressure is gently increased after suddenly increasing pressure. When the pulse pressure increasing mode is selected and a vehicle traveling speed is a preset speed or less (S15), sudden pressure increase time is lengthened (S16), and a pressure increase gradient by leveling a sudden pressure increase and a gentle pressure increase is steepened thereby, and the shortage of the braking force caused by the excessive pressure reduction at antiskid control time in the low speed travel can be restrained.
