A technician must start brake rotor/disc servicing and repair work with removal of the caliper anchor plate. Leave marks on both the brake disc and wheel bolt to preserve the minimum brake disc runout when performing reassembly. A measurement of TIR should be performed following installation if there was a need to use excessive force when removing the brake disc. Rust penetrant and inhibitor F2AZ-19A501-A or an equivalent product to Ford specification ESR-M99C56-A should be applied to brake disc and
Wheel Hub mating surfaces when the brake disc proves stubborn to removal. Use brake parts cleaner F6AZ-2C410-AB or an equivalent cleaner to eliminate any rust as well as remove foreign materials from the brake disc and wheel hub. Obtain high temperature nickel anti-seize lubricant F6AZ-9L494-AA which fulfills Ford specification ESE-M12A4-A alongside its equivalent products. The marks present on both the hub and brake disc should be aligned together before installing the brake disc onto the wheel hub while reinstalling the caliper anchor plate. Verify the total indicated runout (TIR) as the final step of the process.
