Power Brake Booster Push Rod
NOTE:
Booster uses factory adjusted or non-adjustable push rod. Do not attempt to adjust this type of push rod.
- Make push rod gauge according to specified dimensions. See Fig 1 . Remove master cylinder from power unit without removing hydraulic lines and set aside.
- Start the engine and place the gauge over push rod. Adjust push rod nut to provide light tension of about 5 lbs. (2.3 kg) against gauge. Reinstall the master cylinder. See Fig 2 .
- 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.
