PRESSURE REGULATING VALVE A pressure regulating valve is incorporated in the hydraulic line to the rear brakes to limit the pressure applied to them and thus prevent the rear wheels locking under normal conditions when heavy brake applications are made.
The valve is mounted on the front crossmember of the rear sub-frame and is easily removed if required .
Merely disconnect the three hydraulic pipes and remove the nut or bolt securing the valve to the mounting bracket on the sub-frame.
The valve body contains a piston and spring which can be removed once the end cap is unscrewed . If the piston and valve bore are in good condition, the valve can be reassembled after fitting new seals to the piston. Also use a new spring washer at the end cap.
