Insert the pedal prop and depress the brake pedal slightly to prevent brake fluid from escaping when detaching the brake lines. Raise the car and support it safely, then remove the wheels. For the left front wheel, work in the junction box within the wheel housing to separate the brake pad warning sensor electrical harness. For the right rear wheel, remove the right rear wheel well housing liner and then separate the brake pad warning sensor electrical harness in the junction box. At the brake caliper, loosen the brake hose fitting and use shop towels to catch any dripping brake fluid. Remove the pad carrier and caliper mounting bolts from the steering knuckle for the front caliper or from the wheel bearing carrier for the rear caliper. Lift off the caliper and spin the assembly off the hose, plugging any open fluid lines and ports. Inspect the brake caliper for signs of leakage and ensure the caliper piston slides smoothly into the caliper, replacing it if any faults are found. Installation follows the reverse order of removal, and the entire brake system must be bled before driving the car.
