2004 Ford Excursion Brake Booster Parts Questions & Experts Answers

• Q: How to service and repair the hydraulic brake booster on 2004 Ford Excursion?

  A: The beginning of brake booster hydraulic service requires checking that the power brake booster remains separate from the accumulator because dangerous high-pressure nitrogen gas exists inside the accumulator. The disposal of accumulators requires care when exposed to high temperatures while using a drill to make a 1.6 mm (1/16 inch) diameter hole to reduce gas pressure with safety glasses always in use. When the engine shuts off users need to first operate the brake pedal several times to empty the accumulator before disconnecting the ground cable from the battery and taking off any left-side battery which may exist. The removal process requires unfastening both the air cleaner housing and brake pressure switch electrical connector as well as all power steering hoses. Begin the process by taking off brake master cylinder nuts before you remove the power steering hose mounting bracket followed by the brake master cylinder which should be set aside. Remove the instrument panel steering column opening cover then remove the self-locking pin and detach the Brake Pedal Position (BPP) switch while removing the brake booster push rod from the brake pedal pin. Silence the power brake booster through the removal of its nuts before pulling out the power brake booster unit. Installation of the new booster requires following the reverse order of removal steps yet adding fresh O-ring seals to power steering pressure attachments before performing Hydro-Boost bleeding.
