I have a 99 Myco Trailer. How do you add brake fluid???
I popped the black cap off, inside is a nut, kinda rubbery, the top of that nut (flat cap) came off and it has a stem or a tube like piece thats there but not sure how to fill???
The big plastic nut spins off. I believe it is 15/16. It maybe rusty and stuck some be careful and use a 6 point socket. The cap you speak of has a baffled vent in it. You can purchase new plastic pieces from a trailer supply.
Got It!!!
It was super tight and didn't think it would come off.
Used a socket to put inside the nut ...to act as back some sturdy backing than wrenched it off w/ channel locks.
