• Q: How to remove and replace the brake master cylinder on 2009 Lincoln Navigator?

  A: The process to replace the brake master cylinder starts with removing the brake fluid level switch and the air cleaner element. The next procedure requires the removal of two bolts from the coolant expansion tank assembly but maintain it beside while you tighten the bolts to 15 Nm (133 lb-in) when reinstalling. The brake tubes disconnect from their fittings through tube fitting loosening but master cylinder ports need plugging for prevention of contamination. Performing the reinstallation requires tightening the fittings until they reach 20 Nm (177 lb-in). When you take away the master cylinder handle the piston should be handled carefully since exposure could cause brake fluid leakage. Throughout brake master cylinder removal you should unscrew the two nuts before removing the device and install your new component while tightening it to 25 Nm (18 lb-ft). The last step involves performing a brake system bleed to check its functionality after reversing all previous removal procedures. It is essential to use freshly cleaned brake fluid which follows manufacturer recommendations while also cleaning up any brake fluid drips before they touch paint or plastic surfaces with water to stop harm.
