I put a new hitch on my 05 Prairie 360 and sure enough bumped the cover just enough for some extremely putrid fluid to leak out. I decided to go ahead and change it. After I put everything back together, the rear brakes struggle to slow me down. Have I done some kind of damage? Is there an adjustment to be made after changing the fluid? This has been a solid, reliable machine for farm/hunting lease chores -- I hate the thought of retiring it.
