2009 Ford F-150 Brake Master Cylinder Parts Q&A

• Q: How to remove and replace the brake master cylinder on 2009 Ford F-150?

  A: The brake master cylinder replacement begins with disconnecting the brake fluid level switch and removing the air cleaner element. After removing both bolts you can position away the coolant expansion tank/lower air cleaner housing assembly while following up with bolt tightening to 15 Nm (133 lb-in). Begin by disconnecting the brake tubes using the procedure of loosening their fittings while plugging the master cylinder ports to stop fluid contamination. Maintenance technicians should tighten the primary brake tube fitting to 28 Nm (21 lb-ft) yet the secondary brake tube fitting needs 20 Nm (177 lb-in). Disconnection of the front axle vent hose occurs only if applicable. Protect the exposed piston on the master cylinder because damage will result in fluid leaks. Install the brake master cylinder by fastening its two nuts to 25 Nm (18 lb-ft). When complete reverse the installation steps and perform a brake system bleeding process. Use new brake fluid of the manufacturer-recommended type always during maintenance while cleaning any fluid droplets from painted or plastic components right away with water. You should ask for medical advice while also consulting the MSDS document available for the product for emergency medical information.
