Do the real breaks for BMW 440i Gran Coupe have electronic calipers?

What is your question?

My car dealership wants to charge me $2300 to replace the front and rear breaks for my BMW 440i Gran Coupe, which to me seems crazy. I've called around other mechanics and they all need to know if the car has electronic calipers as many won't touch the electronics. How can I find this out? Thank you.
