Front Brake bleeding g

I’ve had a few sportsman’s and I know everyone seems to run into a brake problem at some point. I recently bought a 2002 sportsman 700. The foot brakes for what ever reason was disconnected and line coiled up. The hand brake worked on both front and rear brake but was soft. I decided to try to add fluid and bleeding the brakes. I removed the cover and noticed the seal was in pretty bad shape so I replaced it and the cover. Then I proceeded to bleed the brakes. No fluid is coming out. I tried cracking the cover and all bleeder overnight to gravity feed with no luck. I tried a mighty vac to vacuum bleed all bleeders, still nothing. Now at this point the brakes do not work at all. I disconnected the line from the outlet on the front master cylinder and squeezed the brake, nothing came out. I hooked the vacuum up to the outlet and still no fluid. I put my finger over the outlet and squeezed the brake, I can feel it pushing air and making suction so I belive the master is good. Seems like maybe something is blocking the fluid passages? Any suggestions?
