2009 Ford F-350 Super Duty Brake Booster Parts Q&A

• Q: How to service and repair the vacuum brake booster on 2009 Ford F-350 Super Duty?

  A: Start vacuum brake booster service by taking away the air cleaner element and unfastening the two bolts attached to the degas bottle/lower ACL housing assembly before setting it aside. Reinstall both bolts by applying torque to 15 Nm (133 lb-in). Perform at least five brake pedal releases and pressings when the engine is switched off to drain vacuum from the brake booster. Start service on the vacuum brake booster by disconnecting the brake fluid level switch followed by disconnection of vapor management valve electrical connector then removing the valve from its bracket before setting it off to the side. The brake master cylinder should be positioned aside after removing its two nuts while making sure to tighten to 27 Nm torque during reinstall. First disconnect the brake booster vacuum hose while disconnecting the power distribution auxiliary relay box when present and place it to the side. Begin by removing the brake pedal cotter pin and its cover followed by moving the Brake Pedal Position (BPP) switch together with the brake booster push rod from the brake pedal pin. When reattaching the brake booster-to-pedal bracket tighten the four nuts to 25 Nm (18 lb-ft). After braking booster removal conclude the installation by following the reverse order of steps.
