Ive managed to get the front brake master cylinder from my GPx 250 and fitit too the trike as no sign of a brake lever yet. Problem is I cant get the system to pressurise to bleed it. There is loads of fluid in the reservoir, but when the brake lever is squeezed only a dribble comes out.

I know the cylinder was working fine on the old bike but virtually no pressure on the trike system. Any polite surgestions please as its got me and T.Bird totally stumped!!

Thanks
