2005 Ford Excursion Brake Booster Parts Questions & Experts Answers

• Q: How to service and repair the Hydraulic Brake Booster, specifically the Hydro-Boost(R) on 2005 Ford Excursion?

  A: Starting your work on the Hydraulic Brake Booster requires proper safety protocols regarding the Hydro-Boost(R) unit because you must never lift the pressure booster on top of the accumulator and always keep it off the parts. A correct seating check of the accumulator's snap ring will prevent hazardous situations because high-pressure nitrogen gas resides inside it. A proper method for discarding the accumulator requires drilling a 1.6 mm (1/16 inch) diameter hole into its end to release pressure through which users must wear safety glasses during this process. Use the brake pedal several times after switching off the engine to empty the accumulator. Begin by removing the left side battery followed by the air cleaner housing then disconnect the brake pressure switch electrical connector and power steering hoses. First remove the two brake master cylinder nuts then set aside the hydraulic line bracket with the brake master cylinder. First unscrew the instrument panel steering column opening cover before taking out the self-locking pin to free the Brake Pedal Position (BPP) switch together with the brake booster push rod from the brake pedal pin. The last removal step includes taking out the power brake booster by unscrewing its two brake booster nuts first. The installation process involves following the reversal of the removal process while applying new O-ring seals to the power steering pressure line fittings followed by Hydro-Boost(R) bleeding.
