Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, socket set, torque wrench, safety goggles, gloves.
Safely park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Loosen the lug nuts on the affected wheel slightly.
Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel completely.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader tool, c-clamp (if necessary).
Remove the caliper bolts using a socket set.
Gently slide the caliper off the rotor; support it with a bungee cord to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Sub-steps:
- Measure the thickness of the old pads; if below 3mm, replace.
- Install new brake pads into the caliper bracket, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Examine the rotors for any scoring or damage.
If damaged, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors by reversing the removal steps and torqueing screws to manufacturer specifications.

5. Reassemble and Test

Reattach the brake caliper and torque the bolts to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a crisscross pattern.
Lower the vehicle and pump the brake pedal several times to seat the new pads.
Test drive the vehicle to ensure the grinding noise has ceased.
