I can't say the floor isn't sagging, but the problem isn't the pedal shaft
rubbing on the floor. Or at least it sure doesn't seem like that's what it
is. I can feel it catch and release, and it feels like its the pivot. And
while the pedal does shift some in the whole, it doesn't seem to matter if
its touching the edge or not.
The modification still allows adjustment with the rod and nut. I've played
with that too, but it doesn't seem related, except I've made sure that the
pedal does not have to return all the way to the top to release the
brakes...
I hadn't thought about the relative pressure on the master because the pedal
is through the floor instead of hanging from the firewall, but I'm thinking
the weight is still on the pivot, not the master.
Thanks for the ideas!

Floor sag at front mounts? And pedal shaft rubs on metal flooring? The pedal
travel is somewhat adjustable at the stock MC with a rod and nut, not sure
what you have now. How about pedal too heavy for MC, as most late models had
the pedal hanging off firewall and not weighing on MC units.
