Replacing studs on K-H setup?

I never shop at China Freight. If I need a tool, I'm willing to buy ones that last.

If the old studs are really bad, a heavy brass drift and a big hammer should drive them right out. Yes, the rotor must be on a good solid surface. The hub & rotor are held together by the studs on the K-H brakes, but with two others unmoved you should be good. Make sure the replacements match the old ones removed.
