Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper by loosening the caliper bolts with a socket set.
- Carefully lift the caliper off the rotor and suspend it using a bungee cord to avoid strain on the brake line.
- Check the brake pads for wear; if the thickness is less than 3mm, they need replacement.
Replacement:
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the backs of the new brake pads to prevent squeaking.
- Install the new brake pads in the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Check the rotor surface for grooves or excessive wear.
If damaged, either resurface the rotors if within specifications or replace them with new ones.
If replacing, remove the rotor by unscrewing the retaining screws and sliding it off the hub.

5. Reassemble Components

Reinstall the caliper over the new brake pads.
Torque the caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Remove jack stands and lower the vehicle.
Tighten the lug nuts to the specified torque (typically 76-80 ft-lbs).
Pump the brake pedal a few times to ensure proper brake pad seating.
