Abstract

PURPOSE: To improve a working efficiency, by a method wherein a brake liquid pressure control valve is constituted such that a plug, wherewith a liquid pressure control spring makes contact, can slide freely, and thereby measurement and check of a cut pressure of a piston valve can take place without the use of brake liquid.
CONSTITUTION: The constitution of a brake liquid control valve is such that a valve body 9 seats on a valve seat 6c with a piston valve 6, energized by a differential piston 12, moved to the left, and thereby the supply of a hydraulic oil to a rear wheel with a brake liquid pressure is shut off. Where a cut pressure of said liquid pressure control valve is checked, an air pressure is detected by means of a pressure gauge 20. A plug 7 is then pushed into the inside by means of a pushing jig, and a load F produced at a time when the valve body 9 seats against the valve 6, is detected. A change in the pressure at this time is read by means of the pressure gauge 20, and a closing time of the valve body 9 is found.
