Kelsey Hayes calipers

If you get stuck, a member here rebuilds the whole K-H setup and sells them as a sideline. Seach and you will quickly find. He lives near me (Rancho Cordova). His setups are beautiful, but too pricey for my image. The rotors used to cost $$$ and hard to find, until Centric started making them. I bought a set for $22 ea a few years ago for a roll-my-own brake plan on my back-burner.
