Trailer brakes locking up
The last two times I've had to tow my boat the trailer brakes were dragging after a few stops. The last time the brakes locked up solid and I had to crawl under the trailer and crack a bleeder to release them. The trailer is a 2004 eagle with tandem axle Kodiak disc brakes and titan surge tongue. Calipers, rotors and brake fluid were replaced last year due to wheel bearing failure. The brake fluid looks nasty, moisture contamination? Bad master cylinder? Any input is appreciated.

Could be sticking caliper piston, surge brake cylinder. The nasty fluid is not helping. How old are the calipers? I went with the full stainless caliper and rotor kit 2-3 years ago. They still look like new. Worth the extra $$$.

Is the coupler returning to full out when towing
There should be some type of return spring that keeps coupler relaxed until braking.
solenoid is only active when backing up to release pressure.
My suggestion flush the fluid, but leaning towards master cylinder if coupler moves correctly.
