Solution

1. Preparation

Gather tools and safety gear.
Park the vehicle on a level surface and engage the parking brake.
Gather necessary tools: jack, jack stands, lug wrench, brake cleaner, socket set, torque wrench.

2. Raise and Secure Vehicle

Use the jack to lift the front or rear of the vehicle depending on which brakes are making noise.
Secure the vehicle with jack stands.

3. Remove Wheel

Use the lug wrench to remove the wheel nuts and take off the wheel.
Store the wheel and nuts in a safe place.

4. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket.
Carefully slide the caliper off the rotor without stretching the brake line.
Check the brake pads; if worn below 3mm, replace them.
- Sub-steps for Replacement:
  - Remove old pads and clean the caliper bracket.
  - Install new brake pads in the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or warping; if damaged, replace.
Remove rotor by unscrewing the retaining screws if present.
- Sub-steps for Replacement:
  - Clean the new rotor with brake cleaner before installation.
  - Install the new rotor and secure it with screws.

6. Reassemble and Lower Vehicle

Reattach the caliper and tighten it to manufacturer specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a star pattern to the specified torque (usually around 100-110 ft-lbs).

7. Test Brakes

Before test driving, pump the brake pedal several times to ensure pads are seated against the rotor.
Conduct a test drive to confirm the grinding noise is resolved.
