Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks. Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts on the affected wheel while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel completely.

3. Inspect Components

Brake Pads: Remove the brake caliper by unbolting it from the bracket. Check the thickness of the brake pads; replace if worn below 3mm.
Brake Rotors: Inspect the rotors for any grooves or uneven wear. If necessary, resurface or replace them.
Brake Calipers: Ensure the calipers move freely. If they are stuck, clean and lubricate the slide pins or replace the caliper if damaged.

4. Replace Components

If brake pads are worn, install new pads according to the manufacturer’s specifications.
If rotors are damaged, replace them and ensure they are properly torqued to the manufacturer's specifications (typically around 75-90 ft-lbs).
Reinstall the brake caliper ensuring it is aligned correctly.

5. Reassembly

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (usually 100-130 ft-lbs).
Repeat the process on the other side if necessary.

6. Final Checks

Refill brake fluid if necessary and check for leaks.
Bleed the brake system if air has entered during the repair.
