BRAKING DEVICE FOR VEHICLE

摘要

PURPOSE:To secure braking force even in the case where a brake system or an accumulator fails in a brake device for operating a brake caliper by the brake hydraulic pressure stored in the accumulator. CONSTITUTION:A brake caliper Bc is operated by the brake hydraulic pressure stored in an accumulator A by alternately opening and closing the first and second opening/closing valves V1 and V2. When an electronic control unit U or the accmulator A fails, the third opening/closing valves V3 in an always oepned state is opened, and the caliper Bc can be operated by the brake hydraulic pressure generated by a master cylinder Mc connected to a brakake pedal 8.
