Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Wear safety goggles and gloves for protection.

2. Remove the Wheel

Tools Required: Socket set, torque wrench, jack, jack stands
Steps:
1. Loosen the lug nuts on the wheel using a socket set while the vehicle is still on the ground.
2. Raise the vehicle with a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader, ratchet, and socket set
Steps:
1. Remove the caliper bolts using the ratchet and socket set.
2. Carefully slide the caliper off the brake rotor and support it with a bungee cord to avoid strain on the brake line.
3. Remove the old brake pads from the caliper carrier.
4. Inspect the caliper for any damage or wear, replacing if necessary.
5. Install new brake pads into the caliper carrier.
6. Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer's torque specification (usually around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if needed)

Tools Required: Brake rotor puller (if necessary), torque wrench
Steps:
1. If the rotors are scored or damaged, remove them by unscrewing the rotor retaining screws (if equipped).
2. Clean the hub surface to ensure proper rotor seating.
3. Install new rotors, ensuring they are properly aligned and secured.
4. Tighten securing screws to the manufacturer's specifications.

5. Reassemble and Test

Tools Required: Torque wrench
Steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually 100-120 ft-lbs).
3. Pump the brake pedal several times to seat the new brake pads.
4. Lower the vehicle completely and conduct a test drive to ensure the grinding noise is resolved.
