Hey Cooper, thought you would get some help from BCB or someone who has been down this road with a Bass Cat trailer. If your trailer is 9 years old, I would definitely think your master cylinder could be bad. The only thing between it and calipers is the blocking solenoid. It blocks fluid from the mc to the calipers when you are backing up. First thing I would do is crawl under the trailer and inspect all the lines and such and make sure their integrity is good. If the blocking solenoid failed shut your brakes would not work. I havent heard of this though. If you have the swing tongue, there are some flexible brake lines that could go bad I suppose. If all that checks out the only other thing it could be is your master cylinder. A couple of ways to check it would be to compress it and see if it holds pressure. If it does, while holding it pressurized, open one of the bleeder valves on the calipers and see if you are getting pressure back there. Two person job here. Did I say pull the wheels and check the pads. Might be able to see them from under the trailer w/o pulling he wheels. Dunno. If you go at this, be sure to wash off any brake fluid you get on your trailer. It is very corrosive and will strip the paint right off it. Where are you located?
