Master cylinder for manual disc brakes?

Cardone and a few other rebuilders have part # 10-1821 which is an aluminum master cylinder for manual disc Aspens and Volare's. Forgot exactly what year. You'll need an adapter and a plastic resevoir with the 2 screw-on caps. I got some off of a truck for the extra capacity and they are more common. You might need to break off a tab or two underneath, but it works fine.

I have one on my Dart Sport race car which I'm happy with. But I don't know how it would feel on the street.

Discs need more a bigger bore master cylinder than drums. But don't use any from a FWD appkication and make sure the one you get has a groove to capture the rubber pushrod retaining ring.
