Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Wheel Removal

Loosen the lug nuts on the affected wheel using a socket set.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the braking system.

3. Inspect and Replace Brake Rotors

Inspect Rotors: Check the rotors for warping using a dial gauge. If warped beyond specifications (usually more than 0.002 inches), proceed to replace.
Remove Old Rotors: Unbolt the caliper using a socket set and hang it securely (do not let it dangle) using a bungee cord.
Remove Caliper Bracket: Unscrew and remove the caliper bracket to access the rotor.
Replace Rotors: Slide the new rotor onto the hub, ensuring it is properly seated.
Reassemble: Reinstall the caliper bracket and torque bolts to the manufacturer's specification (typically around 70-90 ft-lbs).

4. Inspect and Replace Brake Pads

Inspect Pads: Check for wear. If pads are below 3mm, replace them.
Remove Old Pads: Slide the old pads out of the caliper bracket.
Install New Pads: Insert the new pads into the caliper bracket, ensuring they are properly aligned.
Reassemble Caliper: Reattach the caliper over the new pads and torque the bolts to the manufacturer's specification.

5. Reinstall Wheel and Final Checks

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Tighten lug nuts to the manufacturer's specification (typically around 80-100 ft-lbs) in a crisscross pattern.
