Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it using wheel chocks.
Jack up the vehicle and remove the wheels.

2. Remove Brake Components

Using a socket set, remove the caliper bolts and carefully slide off the caliper.
Support the caliper using a bungee cord or rope to avoid straining the brake line.
Remove the brake pads from the caliper bracket.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if they are below 1/8 inch, they should be replaced.
If replacing, install new brake pads in the caliper bracket.
Apply brake grease to the backing of the pads to prevent noise.

4. Inspect and Replace Rotors

Check rotors for wear; if they are scored or below manufacturer's minimum thickness, replace them.
If replacing, remove the rotor by unscrewing the retaining screws (if applicable) and sliding the rotor off the hub.
Install new rotors, ensuring they are clean and properly seated.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads.
Torque caliper bolts to the manufacturer's specifications (usually between 20-40 ft-lbs).
Reinstall the wheels and lower the vehicle.
