THE INFORMATION IS NOT VALID. DISREGARD RODNEY DIEHL 7/15/20
Stock GEM brakes are marginal at best.
If you have GOOD wheel cylinders and DRY brake shoes you can increase the stopping power by replacing your Master cylinder with a:
Dodge Master cylinder from an 82 charger
From Ebay About $27
You will also need (2) 3/8 24 X 10-1 MM adaptor fittings BrakeQuip #BQ50
From Brake Connect Clarksville Tn 37040 About $12
This cylinder has a smaller bore thus giving a 30% increase in brake pressure with the same pedal effort.
About an hours work.

I know this is a pretty old thread but I wanted to revisit it due to my own interest.
I’m having a heck of a time tracking down the specific part and I was hoping for some more clues.
From what I have read a 1982 Charger is just a Plymouth Horizon or a Dodge Omni with new badges. (trim package)
The cylinder for those doesn’t look anything like the one I have. Is that normal? Is it this one?
My master cylinder has the two brake lines as well as a tap on the opposite side for electrical. A low brake fluid sensor in the tank and one directly into the cylinder for something else. Does your suggestion take those into account or am I just looking at the wrong part?

My current MS is fine, I was looking for the upgraded one you suggested.
