Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues during repair.

2. Remove Wheel

Loosen lug nuts with a socket set.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket wrench.
Carefully lift the caliper off the brake rotor and support it with a bungee cord or similar to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket. Inspect for excessive wear or damage.
Clean the caliper bracket using brake cleaner.
Install new brake pads (ensure they are the correct type for the vehicle) by sliding them into the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Measure rotor thickness using a micrometer; replace if below the minimum specified thickness.
If replacement is necessary, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
Clean the hub surface and install the new rotor, ensuring it is properly seated.

5. Reassemble and Test Brakes

Reattach the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and torque lug nuts in a star pattern to the specified torque.
Reconnect the battery.
