PROBLEM TO BE SOLVED: To provide brake equipment which can obtain a high responsive pressure rising property without depending on a discharge capacity of a pump.SOLUTION: Bake equipment includes: an operation rod having a first diameter which operates in linkage with a brake operation member; a piston with a step which includes, on one side, a middle diameter part which has a diameter larger than the first diameter, a large diameter part which has a diameter larger than the middle diameter part and an insertion hole into which the operation rod is so inserted from an axial direction as to be relatively movable; a first pressure chamber which acts between the first diameter and the middle diameter part; and a second pressure chamber which acts between the middle diameter part and the large diameter part. According to the brake equipment, a supply amount of a brake fluid into the first pressure chamber and the second pressure chamber is controlled, and when a high responsive pressure rising is required, a supply amount of a brake fluid into the second pressure chamber is increased.
【課題】ポンプの吐出能力に依存せず高応答の昇圧特性を達成可能なブレーキ装置を提供すること。【解決手段】本発明のブレーキ装置では、ブレーキ操作部材に連動して作動する第1の径を備えた操作ロッドと、一側に第1の径より大径の中径部と、中径部より大径の大径部と、操作ロッドが軸方向から相対移動可能に挿入される挿入孔とを備えた段付きピストンと、第1の径と中径部との間に作用する第1圧力室と、中径部と大径部との間に作用する第2圧力室とを備え、第1圧力室と第2圧力室へのブレーキ液の供給量を制御し、高応答昇圧要求のときには第2圧力室へのブレーキ液の供給量を多くすることとした。【選択図】 図3
