Just checked the fluid and the master cylinder is almost dry. I have Tiedown Model 70LP acuator. Is the master cylinder cap supposed to have a small hole in the side? Looks like a 1/16" hole, when I put fluid in the cylinder and press the tongue in, the fluid squirts out of the little hole in the cap. This doesnt seem right. Do I just need a new cap and bleed the system? I'm leaving for a short trip in 2 days - worst case, will it hurt the tounge assembly to pull it without fluid and brakes. I know there's a safety issue not having trailer brakes but the boat isnt that big and I not concerned - just want to make sure I won't have a trailer problem pulling with no fluid.
