1968 Barracuda Notch - Plano, TX

When I installed my hydraulic TOB assembly there was a procedure on how to shim it to get the correct spacing. That would give you a small gap. Now, in operation if it takes up that gap entirely I am not sure. But, if it did it would function like your disc brake calipers. The runout on your rotor causes pad knockback so your brake pads don’t ride on the rotor constantly. I assume the pressure plate finger runout, regardless of how little it is would function the same way.
