I have a 2002 sportsman that the master cyl leaks down slowly. No external leaks so I took the master cyl apart and found the problem. The cup closest to the brakeline fitting is grooved from a piece of dirt. Of course Polaris wants you to buy a whole new 200 dollar MC to fix a 1 dollar cup (ridiculess).

Does anyone know of someone who sells different cups?

I remember back in my auto mechanics days you could buy assortment kits with all different sizes. Thanks

Sorry! One of the few Polaris brake master cylinders that didn't offer a replacement piston and seal kit??
Hopefully some other members can direct you to a supplier that can help you! OPT
