I have a problem with the electric brakes on my Jayco camper. One wheel was not fully locking up on test for rego. Adjusted the brakes and it seemed that the brakes were ok so took it to have the rego check. The wheel in question was almost locked up and of course very hot. Came home and let the brakes cool. Now the wheel is very tight and I can't seem to get the adjuster to back off. Where next as I would like to take the drum off to inspect brakes.
