Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench, anti-squeal lubricant.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the brakes.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Remove the brake caliper by unbolting it from the bracket using the socket set.
Carefully slide the caliper off the brake pads and support it without hanging from the brake line.
Remove the brake pads from the caliper bracket for inspection.

4. Clean and Lubricate

Use brake cleaner to clean the brake pads and rotors, removing dust and debris.
Inspect the brake pads; if they are worn below the manufacturer's specification, replace them.
Apply anti-squeal lubricant to the back of the brake pads and all contact points between the brake pads and caliper.

5. Reassemble Components

Reinstall the brake pads into the caliper bracket.
Slide the caliper back over the brake pads and secure it with the bolts.
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Lower Vehicle and Torque Lug Nuts

Carefully lower the vehicle from the jack stands.
Using a torque wrench, tighten the lug nuts to the manufacturer's specified torque.
