It's easy. Remove calipers from their mount brackets and support them
so the flex hose is not strained. Have helper step on brake pedal and
observe distance the piston(s) moves out. Both pistons on both sides
ought to be the same. And, ideally, they should retract ever so
slightly once the pedal is raised back up again.
Unless the pads are worn to a skin, don't worry about the pistons being
accidentally ejected in your test. It will take a number of pedal
presses before that even remotely becomes a danger.
