Rebuilding the rear brake on my Trailblazer 250... Need the outer gasket for the rear brake caliper. Polaris wants $50 for the set of 6. Holy crap! All I need is the square rubber gasket. Tried all the local hardware stores, and all they carry are the rubber rounds. Anyone got any ideas or connections in North Central (Cass and Fulton county area is where I am primarily at)...
