Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Engage the parking brake and place wheel chocks behind the rear wheels.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the wheel is still on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping using a dial indicator.
- If warped beyond specification (usually more than 0.002 inches runout), replace the rotors.
Replace Rotors:
1. Remove the caliper by unscrewing the caliper mounting bolts.
2. Hang the caliper using a bungee cord to avoid stress on the brake line.
3. Remove the old rotor.
4. Install the new rotor, ensuring it is properly aligned.
Inspect and Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the back of the new pads and install them.

4. Reassemble Braking System

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Torque Lug Nuts

Lower the vehicle from the jack stands.
Use a torque wrench to tighten the lug nuts to the specified torque (usually 80-100 ft-lbs).
