Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, dial indicator, impact wrench (optional), safety goggles, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported by jack stands. Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts slightly while the wheel is still on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Use a dial indicator to check for warping in the brake rotors.
- If warping exceeds 0.002 inches, replace the rotors.
If replacing, remove the caliper by unbolting it from the bracket and hang it securely to avoid stress on the brake line.
Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
Install the new rotor, ensuring it is seated properly.

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if they are below 3mm, they should be replaced.
Remove the brake pads from the caliper bracket.
Apply brake grease to the back of the new brake pads and install them in the caliper bracket.

5. Reassemble and Torque

Reinstall the caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications (typically 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to the manufacturer's specifications (typically 100-140 ft-lbs).
