Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the front or rear end of the vehicle, depending on which brakes are affected.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Store lug nuts in a safe place to avoid losing them.

4. Inspect and Replace Brake Rotors (if warped)

Check for warping: Use a dial indicator to measure rotor runout.
Remove brake caliper: Unbolt the caliper using a socket set, and support it to avoid strain on the brake line.
Remove brake rotor: Unscrew the rotor retaining screws (if present) and slide the rotor off the hub.
Install new rotor: Position the new rotor onto the hub and secure it with retaining screws.
Reinstall caliper: Place the caliper back over the pads and tighten the mounting bolts to the manufacturer’s specified torque.

5. Inspect and Replace Brake Pads (if worn unevenly)

Remove brake pads from the caliper bracket.
Check the pads for uneven wear; if necessary, replace with new pads.
Apply brake grease to the back of new pads to prevent noise.

6. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications.
