All the sudden this week my 06 sportsman 450 has almost completely lost its brakes. When i pull the lever it goes completely to the grip. If i pull the level a few times i get some brake function back. the foot brake seems to work fine. Any ideas? thank you in advance for any solutions/fixes

 

You have air in your brake lines, something caused it, you need to try and bleed them to get the air out, then if that dosen't work you need to find out where the leak is.
