Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Secure the vehicle with wheel chocks.

2. Wheel Removal

Tools Required: Lug wrench, jack, jack stands
Loosen lug nuts on the front or rear wheels where noise is present.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Remove the brake caliper by unscrewing the caliper bolts.
Carefully slide the caliper off the rotor; support it with a bungee cord to prevent stress on the brake line.
Remove the brake pads from the caliper bracket.

4. Replace Brake Pads and Rotors (if necessary)

If brake pads are worn down to less than 3mm, replace them:
- Parts Required: New brake pads
- Install new pads in the caliper bracket.
If rotors are scored or damaged, replace them:
- Parts Required: New brake rotors
- Remove the rotor by unscrewing the retaining screws, if present.
- Install the new rotor and torque to manufacturer specifications.

5. Reassemble Brake Components

Reinstall the caliper over the new pads or rotor.
Tighten caliper bolts to manufacturer specifications.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to the specified value.

6. Final Checks

Pump the brake pedal to ensure proper pad seating and check for any leaks around calipers.
Refill brake fluid if necessary.
