Re: Questions on brake rotors
 

They are different sizes so they may not be interchangeable. I don't
recall which dimension is different. Seems like one is 3 1/16 tall, the
other is 3 3/16.

I just use a pry bar of some kind, putting firm, steady pressure on the
pistons and they just push back in. Most likely you had factory
composite rotors and you were lucky to have no problems with them. Good
choice on the cast rotors.
