Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Wear safety gloves and goggles.

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 lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the brake pads for thickness; they should be at least 1/4 inch thick.
- Look for uneven wear or damage.
Replace Brake Pads:
- If worn, remove the caliper bolts using a socket wrench.
- Slide the caliper off the brake pads.
- Remove the old brake pads and install the new ones, ensuring they are properly seated.
- Reinstall the caliper and torque bolts to manufacturer specifications (usually around 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors

Inspect Rotors:
- Check for grooves or deep scoring; if present, they need replacement.
Replace Rotors:
- Remove the caliper bracket if necessary.
- Slide the old rotor off the hub.
- Install the new rotor, ensuring it sits flush against the hub.
- Reinstall the caliper bracket and torque bolts to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer's specifications (typically 75-85 ft-lbs).
