2002 Ford Excursion Brake Booster Parts Questions & Experts Answers

• Q: How to service and repair the hydraulic brake booster, specifically the Hydro-Boost on 2002 Ford Excursion?

  A: Start servicing or repairing the Hydro-Boost hydraulic brake booster by verifying that you do not carry the power brake booster by the accumulator or drop it onto the accumulator structure since the accumulator contains hazardous high-pressure nitrogen gas. Dispose the accumulator with care by drilling a 1.6-mm (1/16-inch) diameter hole at the end to release gas pressure under watchful eyes that wear safety glasses. After turning off the engine people should press the brake pedal several times to empty the accumulator then unplug the battery ground wire and detach the left-side battery. The air cleaner housing and brake pressure switch electrical connector need removal before power steering hose removal begins. Start by removing the nuts from the brake master cylinder and then take out the power steering hose mounting bracket together with the brake master cylinder keeping it to the side. Take out the Brake Pedal Position (BPP) switch together with the brake booster push rod from the brake pedal pin when you have removed the instrument panel steering column opening cover and self-locking pin. The installation process ends by uninstalling power brake booster nuts and the power brake booster. Reverse the removal process when installing the new booster while also placing new O-ring seals on power steering pressure fittings then bleeding the Hydro-Boost system.
