Power Booster Push Rod
- Normally, brake booster-to-master cylinder push rod should never require adjustment. If brake booster is suspected of having an improper push rod length, check and adjust push rod length as described.
- Make push rod gauge according to specified dimensions. See Fig 1
. Remove master cylinder from power brake booster (without removing hydraulic lines) and set aside. Support master cylinder to prevent damage to hydraulic lines.
- Start engine and place gauge over push rod. Adjust push rod nut to provide light tension of about 5 lbs. (2.3 kg) against gauge. Reinstall master cylinder.
