This sounds like pain. I agree with poultrygirl: Get its teeth looked at. If that's not it, then feel around the shape of their mouth with your fingers. My mare acts the same way as your friend's horse, atreyu, when approached with a bit. She has a very low palate and if I do get the bit in her mouth, she throws a holy fit the entire time. She's bitless and works much better.
Honestly, if the horse was ridden fine in a hackamore before, why change it? If it ain't broke, don't fix it.
