Method of controlling brakes

摘要

The invention provides a method of controlling brakes, wherein caliper pressure is transmitted to a caliper cylinder from a master cylinder depending on an input supplied by operating a brake lever or a brake pedal or the like, thereby effecting normal braking for applying a braking force to each wheel, and a cut-off valve is displaced upward and downward by an expander piston movable in upward and downward directions by a driving means so as to be closed, thereby cutting off said caliper cylinder from communication with said master cylinder and adjusting the volume of an output hydraulic chamber which communicates with said caliper cylinder so as to effect antilock braking for controlling the caliper pressure, said method comprising the step of: controlling the caliper pressure which is applied to each wheel to thereby effect the antilock braking; and moving said expander piston upward and downward upon the antilock braking so as to repeatedly open and close said cut-off valve at given time intervals, thereby increasing the caliper pressure at target pressure increasing rate. <IMAGE>
