For my 68' I bought the rear drum to disk brake conversion from "Stainless Steel Brake Co." They 're the F1 aluminum calipers. After installing this brake setup there's a 3/8" gap between the inside pad and the rotor. How do I close that gap up ? I haven't bled the brakes yet, didn't know if that would help. There's also a nut on the backside of the caliper for adjusting the E-brake. If I turn the nut ,the piston pushes in closing the gap, then I could set the E-brake adjustment. Still I'm not sure because the directions explain nothing, heck, the directions weren't very good for the whole setup.
