Solution

1. Preparation

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

2. Raise the Vehicle

Use a floor jack to lift the front or rear of the Mustang as needed.
Secure with jack stands to prevent movement.

3. Remove Wheels

Use a socket set to remove the lug nuts and take off the wheels.
Store lug nuts in a safe place to avoid loss.

4. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness and condition of the brake pads.
Replace Pads: If worn, remove the caliper bolts with a socket wrench, slide off the caliper, and remove the old pads.
Install new pads ensuring they are properly aligned and secure.

5. Inspect and Resurface/Replace Rotors

Inspect Rotors: Check for any warping or scoring.
Resurface or Replace: If damaged, either have the rotors resurfaced or replaced. Follow manufacturer specifications for thickness and tolerances.

6. Reassemble Braking System

Reinstall the caliper over the new brake pads and torque caliper bolts to manufacturer specifications (typically 20-30 ft-lbs).
Reattach the wheels and torque lug nuts to the proper specification (usually 100-120 ft-lbs).

7. Lower the Vehicle

Carefully remove jack stands and lower the vehicle with the floor jack.

8. Test Brakes

Pump the brake pedal a few times to seat the brake pads.
Conduct a test drive to ensure the issue is resolved.
