S650 base GT with single piston rear brakes, fixing to replace the rear pads. To push the piston back into the caliper, do I need to twist the piston while applying pressure with a caliper tool or just push it back into without turning? I know some fords require twisting the piston back in to get the new pads in.
Thank you!

you need to get the car into service mode and electrically retract the pistons

To enable brake service mode on a 2024 Mustang,
turn the ignition to the ON position (without starting the engine), simultaneously press and hold the accelerator pedal to the floor and the electronic parking brake (EPB) switch in the "apply" (upward) position. While holding both, turn the ignition off, wait a few seconds, and then turn the ignition back on. The brake light should begin flashing and a message will appear on the dash, indicating that the mode is active

electric PB


How to enable service mode
  • turn on accessory mode (start button without pressing the brake)
  • press the brakes and release the electronic parking brake in the direction that would normally release it then release
  • release the brakes
  • press the accelerator and press the electronic parking brake in the direction that would normally release it and hold both
  • turn the vehicle off, then within 5 seconds turn it on to accessory mode again, all while still holding the accelerator and parking brake
  • turn the vehicle off and release the accelerator and parking brake
  • you should now have a message on the dash saying something about the brakes being in service mode, and in this mode brake performance will be much weaker
How to disable service mode
  • turn on accessory mode (start button without pressing the brake)
  • press and hold the accelerator
  • pull the electronic parking brake in the direction that would normally apply it and hold it, while still holding the accelerator
  • "firmly" press the brake pedal for at least one second, then release it, all while still holding the accelerator down and parking brake up
  • turn the vehicle off, then within 5 seconds turn it on to accessory mode again, then release the accelerator and parking brake

Thank You guys……one I get it into service mode and calipers off, then how do I compress the piston, do I need to rent one of tue kitsfrom autozone with the tool that spins the piston(with the tabs on the piston face) or can I just apply pressure with a C-clamp or compression tool?

I have not done one yet so that I don't know

I would suspect the retraction by service mode should be enough, pulling the piston back into the caliper.

I used brake maintenance mode and got the calipers off, no need to “Twist” the piston back in, just apply pressure with a caliper spreader tool and it pushes back in. Tool below is what I used.
