Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is on a level surface and securely lifted.
Wear safety goggles and gloves.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it dangle on the brake line).
Inspect the brake pads; if they are worn down to the indicator or below, replace them.
If replacing, slide new pads into place ensuring they fit snugly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping.
If damaged, remove the rotor by loosening the retaining screws.
Clean the hub surface and install a new rotor, ensuring it is properly seated and secured.

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s specified torque setting (usually around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

Lower the vehicle back to the ground.
Tighten the lug nuts to the manufacturer's specified torque setting (usually around 80-100 ft-lbs).
Start the vehicle and pump the brakes a few times to ensure proper contact is made.
