Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket using a socket wrench.
Carefully lift the caliper away from the rotor and secure it using a bungee cord or similar tool to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Compare new brake pads to old ones to ensure they are the correct size.
Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors

If rotors are scored or warped, remove them by unbolting from the hub.
Install new rotors by aligning them with the hub and securing them with the bolts to the manufacturer’s torque specifications.
Clean the rotor surfaces with brake cleaner before installation.

5. Reassemble and Test

Reattach the caliper over the new brake pads and secure it with the caliper bolts.
Reinstall the wheel and tighten the lug nuts to the manufacturer's specifications.
Lower the vehicle and reconnect the battery.
