Need help re: trailer brake

[19Mako]

I have a 2002 magic tilt trailer with brakes. The brake line is attached to the coupler and runs along inside the trailer where it comes out at the rear axel. The brass connector snapped in half (I stepped on it while cranking in the boat)

Does anyone know if I can cut the brake line and add a new male/female fitting or if I need to order a new brake line? I read on a site that they do not recommend cutting the line since it is impossible to flange the inside tubing to get a good fit.
Any mechanics in here?


thanks in advance,
for now I am sidelined.
