- Make push rod gauge according to dimensions shown in Figure. Remove master cylinder from power unit without removing hydraulic lines and set aside.
- Start engine and place gauge over push rod. Adjust push rod nut to provide slight tension (approximately 5 lbs.) against gauge. Reinstall master cylinder.
- With engine idling and master cylinder reservoir cover removed, observe fluid surface when brake pedal is applied rapidly. Movement of fluid surface in forward reservoir indicates properly adjusted push rod. If fluid surface movement did not occur, push rod is adjusted too long and procedure must be repeated to prevent brake drag.
