Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, brake cleaner, and safety goggles.
Safety Warnings: Ensure the vehicle is on a flat surface; engage the parking brake and wear gloves and safety goggles.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are making noise.
Secure the vehicle with jack stands to ensure stability while performing the repair.

3. Remove Wheel

Using a lug wrench, loosen and remove the lug nuts from the wheel.
Carefully take off the wheel and set it aside.

4. Inspect Brake Components

Brake Pads:
- Look for significant wear on the pads; replace if they are less than 1/8 inch thick.
Brake Rotors:
- Check for grooves, scoring, or warping. If damaged, they may need to be resurfaced or replaced.
Calipers:
- Ensure calipers are not stuck and can move freely. Check for signs of leaking brake fluid.

5. Clean and Lubricate

Clean the rotor surface using brake cleaner to remove dust and debris.
Apply anti-squeal lubricant to the back of the brake pads where they contact the caliper.

6. Reassemble and Test

Reinstall the brake components, ensuring everything is correctly aligned.
Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
