2
Check brake rotors for grooves, scoring, or warping.
3
Examine brake calipers for sticking or improper functioning.
4
Inspect brake hardware (clips, shims) for corrosion or damage.
5

Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on the brake noise source).
Secure the vehicle with jack stands.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for thickness; if less than 3mm, replace them.
- Look for uneven wear indicating caliper issues.
Replace Brake Pads:
- Remove caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it using a hanger.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated correctly.

5. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for scoring, grooves, or warping. Measure with a micrometer if needed.
Replace Rotors:
- Remove the caliper bracket if the rotor is stuck.
- Remove the rotor from the hub by sliding it off.
- Install the new rotor and torque to specifications (typically 70-90 ft-lbs).

6. Reassemble Braking Components

Reinstall Caliper:
- Position the caliper over the new pads and rotor.
- Tighten caliper bolts to the manufacturer’s torque specifications (around 25-35 ft-lbs).
Reinstall Wheel:
- Place the wheel back on the hub.
- Hand-tighten lug nuts, then lower the vehicle and torque them to specification (usually 80-100 ft-lbs).

7. Test Brakes

Start the vehicle and press the brake pedal several times to seat the pads against the rotor.
Check for any noise or abnormal behavior.
