Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the battery to avoid any electrical issues.

2. Raise the Vehicle

Use a jack to lift the front and rear of the vehicle.
Secure with jack stands to ensure stability.

3. Wheel Removal

Use a socket set to remove the lug nuts and take off the wheels to access the brake components.

4. Brake Pad Inspection and Replacement

Inspect Brake Pads:
- Remove the caliper bolts using a torque wrench.
- Slide the caliper off the rotor and support it with a bungee cord (do not hang by the brake line).
- Remove the brake pads from the caliper bracket.
Replace Brake Pads:
- If wear is uneven, replace the affected pads with OEM or high-quality aftermarket pads suitable for the Mustang S650.
- Apply brake grease to the back of the new pads to prevent noise.

5. Caliper and Rotor Inspection

Inspect Rotors:
- Check rotor for wear and warping using a dial indicator.
- If worn beyond specifications, replace rotors.
Caliper Maintenance:
- Clean caliper slides and lubricate them with brake grease.
- Ensure the caliper piston moves freely; compress if necessary.

6. Reassembly

Reinstall the caliper over the new brake pads and torque the caliper bolts to specifications (typically around 20-25 lb-ft for most Ford calipers).
Reattach the wheels and torque the lug nuts to the manufacturer’s specifications (usually around 100-120 lb-ft).

7. Brake System Bleed (if necessary)

If any brake fluid was lost during the process, bleed the brake system to remove air.
Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve.
