Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, C-clamp or brake caliper tool, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks. Always wear safety goggles and gloves.

2. Remove the Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Jack up the car and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove caliper bolts using a socket wrench.
- Carefully slide the caliper off the brake pads and suspend it using a bungee cord (do not let it hang by the brake line).
- Check the brake pads for uneven wear. Replace any pads that are excessively worn.
Replace Brake Pads:
- If uneven wear is identified, remove the old pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to the contact points.
- Install new brake pads, ensuring they are oriented correctly.

4. Check and Replace Brake Rotors (if necessary)

If the rotors are warped or damaged, remove the caliper bracket and rotor.
Replace with new rotors, ensuring they are properly torqued to manufacturer specifications.

5. Reassemble Components

Reinstall the caliper over the new pads and tighten the caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten lug nuts.

6. Lower the Vehicle and Final Checks

Lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer's specifications.
Pump the brake pedal several times to seat the new pads properly.
