Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Lift the Vehicle

Use a jack to raise the front or rear of the car (depending on where the noise is coming from).
Secure the vehicle with jack stands to ensure safety.

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: Check the thickness of the brake pads; if they are below 3mm, they should be replaced.
Replace:
1. Remove the caliper bolts using a socket and ratchet.
2. Carefully slide the caliper off the rotor; support it with a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are correctly oriented.
5. Apply brake grease to the back of the pads to reduce noise.

5. Inspect and Replace Brake Rotors (if necessary)

Inspect: Check for grooves or uneven surfaces on the rotors.
Replace:
1. If rotors are worn, remove the caliper bracket by unscrewing the bolts.
2. Slide the rotor off the hub; if stuck, gently tap with a rubber mallet.
3. Install new rotors, ensuring they are clean and free of grease.
4. Reattach the caliper bracket and tighten to manufacturer specifications (typically 35-50 ft-lbs).

6. Reassemble and Lower Vehicle

Reinstall the caliper over the new pads and tighten caliper bolts to the specified torque.
Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a star pattern to ensure even pressure.

7. Final Checks

Reconnect the battery.
Pump the brake pedal several times to seat the new pads.
Check brake fluid level and top off if necessary.
