Before you service the front brake disc, support and lift the vehicle up, remove the wheel and then the tire. After that, get rid of the
Brake Caliper, the adapter and then uninstall the retainers from the
Wheel Studs to separate the disc. Installation needs you to start with the disc hub, hold it in place with retainers, then proceed to the brake caliper adapter and brake caliper. Refit the wheel and tire, lower the vehicle once the support is out and step on the brake pedal a few times to seat the brakes.
