I had my Crossfire inside all winter being stored and finally took it out and went for a spin.
I soon realized that I had some new braking issue that I didn’t have when I stored it last fall.
when I first press the brake it quite rapidly sinks to the bottom, and if I release it right away and let let pedal come back up and then press it back down right away it then holds and brakes. But if I release it for a few seconds or so and then try and press the brake again it drifts right back down to the floor pretty much. Not sure if this is air in the lines or if it’s a master cylinder issue? I don’t see any brake fluid leak or loss anywhere. The tank is right full.
Any insight or help would be much appreciated.
