I bought this atv a while back and the foot break has never worked. Does anyone make a rebuild kit for the mastercylinder. I took this one apart and one of the cups seems to have a cut in it so I think it is probably bypassing.

 

Just replace small master cylinder and bleed,not that expensive.

 

You don't say the year and milage of your machine.
Did you try bleeding it?
Lots of parts available on e-bay if the bleeding doesn't work.
I always thought that the rear brake on the Polaris's weren't worth a hoot anyway. I have one that goes to the floor but I just use the hand brake anyway.

Try bleeding it with the cap off the resivoir.THey seem to get air in them regularlly .Most just dont worry with it since the rears work with the hand lever too.

 

i have a 2000 trailboss and mine doesnt work either i just use the hand brake.some guys on here say to put something heavy on the foot brake overnight and it will build up pressure i havent tried it yet though.
