Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Raise the vehicle with a jack and support with jack stands.

2. Remove Wheel Assembly

Sub-steps:
1. Loosen lug nuts with a socket wrench while the vehicle is still on the ground.
2. Lift the vehicle and remove lug nuts completely.
3. Remove the wheel to access the brake components.
Tools Required: Socket set, jack, jack stands.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor; do not kink the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare the thickness of new pads to old ones; replace if worn under manufacturer's specifications.
5. Apply brake grease to the back of the new pads and on the caliper slides.
6. Reinstall the caliper over the new pads and secure with bolts.
Tools Required: Socket set, brake grease.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are scored or warped, remove them by unscrewing the retaining screws (if applicable).
2. Clean the hub surface before installing new rotors.
3. Install new rotors and secure them properly.
Tools Required: Torque wrench, impact driver (if screws are tight).

5. Reassemble Wheel

Sub-steps:
1. Place the wheel back on the hub.
2. Hand-tighten lug nuts and lower the vehicle.
3. Once on the ground, use a torque wrench to tighten lug nuts to manufacturer specifications.
Tools Required: Torque wrench, socket set.

6. Final Inspection

Sub-steps:
1. Pump the brake pedal several times to seat the brake pads.
2. Check brake fluid level and add fluid if necessary.
3. Test drive the vehicle to ensure the squeaking has stopped.
Tools Required: Brake fluid (if needed).
