Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks for added safety.

2. Raise the Vehicle

Tools Required: Jack and jack stands.
Loosen the lug nuts slightly while the vehicle is still on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel completely.

3. Remove Brake Components

Tools Required: Socket set and ratchet, brake caliper tool.
Remove the caliper bolts and slide the caliper off the rotor.
Support the caliper with a bungee cord or rope to avoid straining the brake line.
Remove the brake pads from the caliper bracket.

4. Inspect and Replace

Check brake pads for wear indicators; if they are worn down to 3mm or less, replace them.
Inspect the rotor for scoring or thickness; replace if below minimum thickness specifications.
Parts Required: New brake pads, possibly new rotors.
If rotors are to be replaced, use a rotor puller if necessary to remove them from the hub.

5. Reassembly

Install new brake pads into the caliper bracket.
Slide the caliper back over the new pads and secure with bolts, tightening to the manufacturer's specified torque.
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern.

6. Lower the Vehicle

Remove the jack stands and lower the vehicle slowly.
Torque the lug nuts to the manufacturer's specifications once the vehicle is back on the ground.
