My electric brake on camper is stuck in the on position. I was adjusting and the star wheel will not roll up or down. I am not able to remove the hub since brakes are on. Any ideas?

It sounds like you may be having some wiring issues; but first, start by checking your connectors to see if there is any corrosion that may be hampering their functionality and keeping your brakes engaged. To disengage your brakes, cut the power wire and that should disengage them. Then go over the wiring to try and look for any that are crimped, broken, or otherwise damaged. If you cut the wires that are feeding your brakes power and they still do not disengage, you will need to go to a local trailer or mechanic and have them attempt to diagnose the issue.
