power drum/drum to power disc/drum question

[Dino]

I'll be running a drumm booster with 4 piston calipers.  The master has a bore of 1 1/8" which may be way too much so I'll be looking for another mc soon!

Interesting...the master I have is from a 1972 Coronet, which is 1.125 bore. Need to get another one?

Same size as mine, I think I bought one for a 70 Charger so likely the same master.  I don't know how it'll act to be honest.  I'll probably install mine, bleed the system, and see how it goes.  If the pedal is too hard then I'll get another master.  And I do believe, from what I've read, that it'll be too hard but depending on the other brake components it may or may not be okay.  I'd say use what you have and see how it stops.  MC's are pretty cheap and easy to swap if need be.

How about Cardone part number 13-1515. 72 Charger disc brake master cylinder. 1.03 bore. Will this work instead of the 1.125 bore I have now?

That should fit but be careful with A1 Cardone, I have yet to hear a single positive word about them.
