2
Examine the brake rotors for grooves, scoring, or warping.
3
Check for any foreign debris lodged between the brake pads and rotors.
4
Inspect the brake calipers for proper operation and signs of leakage.

Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Use wheel chocks to prevent movement and engage the parking brake.
Gather tools: jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
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

Sub-steps:
- Remove the caliper bolts using a socket set and gently lift the caliper off the rotor.
- Support the caliper with a bungee cord or hang it to avoid stressing the brake line.
- Inspect the brake pads; if worn below 1/4 inch, replace them.
- Remove the old brake pads and clean the caliper bracket with brake cleaner.
- Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the rotor for damage; if grooves or excessive wear are present, replace the rotor.
- Remove the caliper bracket if replacing the rotor.
- Remove the rotor by pulling it off the hub.
- Install the new rotor, ensuring it is seated properly.
- Reattach the caliper bracket to the new rotor.

5. Reassemble and Test

Sub-steps:
- Reinstall the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications (typically 20-25 lb-ft).
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 76 lb-ft).
- Pump the brake pedal several times to seat the pads before driving.
