Hey guys. I have a 2011 Skeeter ZX200 with a tandem axle EZ Loader trailer. The disc brakes seem to not work anymore and I doubt the previous owner ever did any maintenance. The reservoir on the tongue is full, but very murky/rusty looking. When stopping I can hear/feel the tongue slam in, and when accelerating from a dead stop I feel it pull apart. I don't feel the brakes at all when stopping anymore. Where should I start my investigation? Bleeding the brakes? Pads? I'm savvy with a wrench, but never done any brake work on a boat trailer.
Any help is much appreciated!
