Installation Notes and Tips

Verify rear left fitment by year, make, model, and brake configuration before installation. Confirm bracket compatibility on Ford Explorer, Ford Flex, Ford Taurus, Lincoln MKT, and Lincoln MKS applications, and compare the original inlet thread and bleeder screw specifications to the replacement unit. Inspect brake hoses, pads, and rotor condition during caliper replacement, and bleed the hydraulic system after installation.
