Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to secure the vehicle and set the parking brake.

2. Inspect and Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Loosen the lug nuts slightly before lifting the vehicle.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel by fully loosening the lug nuts.

3. Inspect Brake Components

Tools Required: Brake cleaner, measuring calipers
Check the brake rotors for warping using calipers or a run-out gauge.
If warped, proceed to replace the rotors.
Inspect brake pads for uneven wear; replace if necessary.

4. Replace Brake Rotors (if necessary)

Tools Required: Socket set, torque wrench
Remove the caliper and bracket to access the rotor.
Unscrew the rotor retaining screws if applicable.
Slide the old rotor off and replace it with a new one.
Reinstall the caliper and bracket, torquing to manufacturer specifications.

5. Reinstall Wheel and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer's specifications in a crisscross pattern.

6. Final Inspection

Check all brake components to ensure proper installation.
Test the brakes at low speed to verify the repair was successful.
