I just picked up a brand new Cougar A/E yesterday. Drove it home 5 hours, backed it into my garage, no problems. Today I pulled her out and washed her. When I tried to back it in, brakes locked. So I pulled forward, no proble. Put it in reverse, brakes lock. So I decided to pull the boat all the way out to the street, unhooked and rebooked everything. Pulls forward fine, and backs up fine until I come to a grade then the brakes lock up. Now I have no way of getting my boat back into the garage because I have to back up a small hill and the brakes lock up every time.first of all, is there any way to disable the brakes?Secondly, what could be the problem? I never hit anything, ran over anything, nothing. Just pulled it out this morning and now the brakes lock up.Frustrated!!!!!
