Vacuum Power Booster Push Rod
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Ford Pickup Heritage, 2004 Ford Pickup, 2003 Lincoln Blackwood, 2003 Ford Pickup, and 2002 Lincoln Blackwood. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not apply the brake pedal with the master cylinder removed.
- Push rod has an adjustment screw to maintain correct distance between booster push rod and master cylinder piston. If push rod is adjusted too long, it prevents master cylinder piston from completely releasing hydraulic pressure, causing brakes to drag. If push rod is adjusted too short, it causes excessive pedal travel and an undesirable groaning noise in booster area.
- Adjust the power brake booster to brake master cylinder push rod length. Remove master cylinder. Measure the power brake booster to brake master cylinder pushrod with engine running (vacuum applied). See Fig 1. If necessary, adjust the screw to the correct length.
