My FSM is at the resto shop with the car.  But let me look at another year.  I'll have to dig it out though. . . .

I replaced a booster on a 72 Newport years ago. . .  I went through hell getting the right one.  Are you sure you have the correct one for the Chrysler?  I think Ford used one like it too

Yes, I do know its correct. the car has had lousy brakes since 1986 when I had a major brake job done. That shop apparently replaced the booster with a Midland unit which is a single diaphragm. I know the 300H's should have that (1.) because mt shop manual says so , and (2.) I have seen pictures and most 300Hs have the dual diaphragm booster . This should make a big difference in pedalpressure I understand.
 
Since I made this post, I investigated acorn nuts at Grainger. There vcan be over .100 variation in the head height depending on manufactier, and that could be a big problem for me.
 
Best, Mike Moore

I think that's about right, but also it looks to me like within the same size acorn nuts, there are huge variations in height. That may be what I have to do- buy some taller acorn nuts, or have one made . But does it really matter that much?

this is why they used a Midland unit...NAPA says that's the replacement for a 300H

is it supposed to have a Bendix dual unit? 60's Imperials used that one

Hello Mike.  I used to own a '62 New Yorker.  (Someone on this site has it now - I don't remember who.(http://www.moparfins.com/forum/smileys/smiley36.gif))  I had the same problem adjusting the acorn nut on that car's booster.  It was rusted solid.  Not knowing that I turned it hard and it broke.  I needed to find another one; luckily I knew where a '63 with power brakes sat in a junk yard.  That nut turned easy.
 
I would suggest you remove the shaft that nut is on and soak it in a good lubricant or rust-buster.  It should move fairly freely.
 
Welcome!

That was me you ding-a-ling.  I have the New Porker.  Or were you being funny.  How could you forget?  You rub it in all the time.  Come to think of it, I need to get that out of there

A little heat on the shaft a few times will free it up too.  Heat then cool.  Heat and cool.
 
If you soak it with PB Blaster penetrating oil, then heat it and cool, it works better.  It vaporized the lubricant and slightly expands the metal.  This does two things.
 
It breaks the rust loose and the vapors sneak into the next thread.
 
I have to teach these kids everything.  LOL

Actually, it was in very good shape body-wise.

I like it. . .  I've sat in it twice in 5 years.  It's stuck in Oregon.  I need two weeks to get that puppy, unless I have another driver.

Whoa, Stevo, get out your calculator, you bought that in September, 2003.  How many years has it been?

Its done. I set the clearance at .060 which I measured several times. My pedal is now much higher. The original clearance was .310.
