Solution

1. Preparation

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

2. Remove Wheels

Loosen the lug nuts on the affected wheel using the lug wrench.
Raise the vehicle with a jack and support it securely on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect the brake pads for uneven wear; measure thickness with a caliper tool.
If replacement is necessary, use brake cleaner to clean the caliper and rotor surface.
Remove the caliper bolts using the appropriate socket size.
Carefully slide the caliper off the rotor without damaging the brake line.
Remove the old brake pads from the caliper bracket and install new pads, ensuring they seat properly.
Use the caliper tool to compress the caliper piston if it does not fit over the new pads.

4. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer specifications.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then torque the lug nuts to the specified value.
Repeat the process for any additional wheels if needed.
