Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove lug nuts completely and take off the wheel.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set and slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. Compare the thickness of the old pads to new ones; replace if worn down.
4. Apply brake grease to the backing of the new pads and install them into the caliper bracket.
Tools Required: Socket set, brake pad spreader.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotors for scoring or excessive wear; if damaged, remove them by unscrewing the rotor retaining screws.
2. Install new rotors, ensuring they are clean and free of grease.
3. Torque the retaining screws to manufacturer specifications (usually around 10-15 ft-lbs).
Tools Required: Torque wrench.

5. Reassemble Braking System

Sub-steps:
1. Reattach the brake caliper over the new pads and torque caliper bolts to specification (typically 25-35 ft-lbs).
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and fully tighten the lug nuts in a star pattern to ensure even distribution.
Tools Required: Torque wrench, lug wrench.

6. Final Check

Sub-steps:
1. Pump the brake pedal several times to seat the brake pads.
2. Check brake fluid level and top off as necessary.
3. Test drive the vehicle to ensure the grinding noise is resolved.
Tools Required: None additional.
