07 brake issues

2007 sportsman . when I push foot brake I get pressure in the hand brake master cylinder. Nothing at the caliper

same thing with hand brake. If I push it, it forced the fluid to the foot brake resivor.

If I push foot brake then use the hand brake everything works.

Right now I have foot brake zipties down so hand brake works.

Trying to figure out what I need to replace to get foot brake working.

Is there a check valve in there somewhere?
