Well, after reading about a few people with the exact problem on various forums I decided to get a vacuum bleeder and try that. I bled the system twice until I couldn't extract anymore air. The brake now works, but is pretty spongy. It pulls almost to the handlebar but does apply some force to the brakes. I can still turn the rotors using hand strength but it requires some strength to do so.
Bench bleeding the master cylinder the brake was much firmer. I can only suspect part of the problem is the master cylinder and part of it is the rubber lines allowing expansion. If there is air left if the system it is trace amounts so I am assuming it isn't the larger issue.
So the question is, for those that have had experience with this master cylinder, is this spongy feel normal for this older unit? I ask because my newer 2000 era Polaris has excellent brake force with no spongy feel.
