The flathead inner bolt is rusted solid to the 14 mm jam nut. I can loosen the jam nut but the adjuster won't budge. Can I turn the two all the way out together using the jam nut or is the inside of the adjuster bolt connected to something that will break or bend if I try this? I don't have a manual or diagram to see what I am dealing with so any help is greatly appreciated. Thanks, Jerry.
