Hey guys. Doing work on the 280S and I need help.

Neither my father nor I have the knowledge of this and we need to know if there's usually a ball bearing or something acting as a valve in a rubber brake line...not steel.

I had to change out a steel line and we're able to bleed all lines but one. It seems to be clogged cuz I cant get the wire that I'm cleaning it with all the way through.

Could it also be like a mini mini strainer/filter or something?

None of the above make sense but its all we can think of.

That or it's completely clogged.

Your help = AWESOME.
