Solution

1. Preparation

Gather tools and parts, ensuring a clean working environment.
Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Brake cleaner
- Caliper tool
- Socket set
Safety Warnings:
- Ensure the vehicle is on a flat surface and properly secured with jack stands.
- Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts slightly before lifting the vehicle.
Use the jack to lift the vehicle and place it securely on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Components

Check brake pads for wear; they should have at least 3 mm of material remaining.
Inspect brake rotors for grooves, cracks, or excessive wear.
Clean the brake components with brake cleaner to remove dust and debris.

4. Replace Brake Pads (if worn)

Remove the caliper bolts using the appropriate socket size.
Slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
Remove old brake pads from the caliper bracket.
Compress the caliper piston using a caliper tool until it is fully retracted.
Install new brake pads ensuring they are oriented correctly (inner/outer).
Reattach the caliper over the new pads and torque bolts to manufacturer specifications.

5. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts to the specified torque.

6. Test the Brakes

Start the vehicle and pump the brake pedal several times to seat the pads.
Test drive the vehicle to ensure the squealing noise is eliminated.
