Section 06-00: Brake System, Service | 1996 F-150, F-250, F-350, F-Super Duty Chassis Cab, Motorhome Chassis and Bronco Workshop Manual |
Inspect the power brake booster (2005) for damage, misalignment or loose mounting nuts. Make sure the vacuum supply hose connection is secure. A trace of brake fluid below the brake master cylinder mounting is normal and is caused by the wiping action of the brake master cylinder piston seals.
