I don't know if you can tell like that. The master cylinder plunger on an ATV don't have much travel, so the plungers on an ATV wheel cylinder won't move very much. If one goes out too far, the others might not move. Also, if air is in the lines, they won't move out. Before you can bleed the air out of the lines, you need to have the drums on and the brakes shoes adjusted up. I would go ahead and put everything back together and adjust the brakes up and bleed the system and go from there.
