Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Safety glasses and gloves should be worn throughout the process.

2. Remove Wheel

Tools Required: Jack, Jack stands, Lug wrench
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 wheel completely.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove caliper bolts using a socket wrench.
- Lift the caliper off the rotor and support it with a bungee cord to avoid hanging on the brake line.
- Check the thickness of the brake pads; if they are below 3mm, replace them.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Apply brake grease on the back of new pads to prevent noise.
- Install new pads into the caliper bracket.

4. Check and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check the rotor surface for scoring or excessive wear.
- If rotors are below the minimum thickness specification or have significant scoring, they should be replaced.
Replace Rotors:
- Remove the caliper bracket if necessary to access the rotor.
- Remove and replace the rotor, ensuring it is properly aligned.

5. Reassemble Components

Reattach the caliper over the new brake pads and secure with bolts, tightening to manufacturer specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a star pattern.

6. Lower Vehicle and Test

Carefully lower the vehicle from jack stands.
Pump the brake pedal a few times to seat the brake pads.
Test drive the vehicle at low speed to ensure brakes are functioning properly and noise is eliminated.
