Before you remove the front brake rotor, you should get the vehicle up and support it. After that, take out the wheel mounting nuts and remove the tire and wheel assembly together. It might help if you retract the caliper piston a bit so the pads and rotor have enough space to let the caliper slide off without problem; do this by pulling the caliper away from the outer part of the knuckle while using its guides, not directly pushing the piston. After that, remove the two bolts that join the disc
Brake Caliper and adapter bracket to the
Steering Knuckle, then pull them both off the rotor together, securely hanging them out of the way so you don't stretch the brake hose. Once done, take out the clips still connecting the brake rotor to the wheel studs and move the brake rotor off the hub and bearing.
