[Amc-list] Brakes!

["Swygert, Francis G MSgt 436 CES/CECM" <Francis.Swygert3@xxxxxxxxxxxx>]

The most important thing is what you listed last, or rather the second
portion of it: "post-79". My meaning is if you are upgrading brakes use
modern standards, which when boiled down is the minimum -- a rear
proportioning valve of some type for disc/drum operation. For four wheel
drum or disc no balancing valve is needed. That's in any hot-rod brake
guide! Now if you're restoring, worry about what the TSM says, otherwise
the texts at www.mpbrakes.com work. Note that with drum/drum and
disc/disc setups you still have to size the brake components correctly!
If you have the same size/power (caliper piston or wheel cylinder size)
brakes on all four corners, naturally the rears will lock before the
fronts. 

I recently had an e-mail conversation with MPBrakes. They will sell
parts to someone upgrading their AMC, but since the parts aren't listed
as AMC parts, the caveat is there are no guarantees -- it's user beware!
That's the same thing they do for hot-rod/street-rod setups. I have
permission to use some of their documents for an article, so I'll be
doing a big brake write-up soon!

OK, a very crude and error-filled first pass ad the Grand
Unified Brake AMC List (GRUB).

The formatting went all to hell when I did "save as HTML". I'll
clean it up later. The year column is AFU, oh well.

Note that there are at least FIVE VISUALLY DIFFERENT combo
valves, and FOUR FUNCTIONALLY DIFFERENT combo valves. The various
TSMs spell out in very explicit text the differences. No wonder
we're all confused.

Then there's two different warning-only switches, and two
separate rear-prop-only valves.

There may be more; I don't have all the TSMs yet.

I will eventually add drawings and/or photos of all of them.


Stick to pre-67, or post-79, and it's easier.
