A: You need to bypass the low pressure switch, but it sounds like the valves 
may be closed or the hoses reversed.

Trying to get the ac working on my daughters 83 Spirit
that Firestone wrecked last year.  I finally located a
replacement evap and started putting things back
together.  The following have been replaced in the
system:
Condensor -new
Compressor-rebuilt
Charging valves-new
Evap and expansion valve-used
The system was running on several occasions last
summer but Firestone was never able to get it sealed
after they wrecked the evap lines and the charge would
only last a day or so.  After getting everything back
together I pulled vacuum on the system for approx 30
min and then let it sit for over an hour and the
vacuum held.  I then put in one can of HC-12
(environmently friendly, direct replacement for R-12
that requires only 40% of the R-12 charge, ie two
cans).   Hooked up the second can, started the car,
opened the second can and turned the ac on high...no
compressor cycling on.  Checked the system pressures
and low side was high and high side was low , but
there was pressure.
TSM did not have a t/s procedure for the compressor.
Looking for suggestions on how to figure out why the
compressor will not turn on.

Same as the small cars, yes. You can use the small car brakes, and if
it's just a driver I recommend you use 79-83 Concord/Spirit/Pacer
brakes. The calipers are a little narrower, but for normal driving won't
overheat. The Matador kept the "Big Bendix" brakes with the thicker
calipers for better cooling, but the smaller ones are fine on the large
cars. The small car brakes are the same as other manufacturers large car
brakes, and thicker than many new cars -- they are the same on XJ
Cherokees, which weigh about as much as the Mat. They cool much better
than the solid 66-70 discs. You can more easily get parts for the 79-83
small car brakes. Just remember that you need a small car master
cylinder to go with them! The big piston brakes use a bigger piston
master. As you mentioned, big car reman calipers are pretty easy to get
and realatively cheap, it's the rotors that are hard to find and
expensive (over $100 each last time I checked). The 73 should have
Kelsey-Hayes discs on it I believe. They use a different master cylinder
also.

WHat models interchage with the front brakes on a 73
Mat?  It currently has discs.  Is it as easy as the
swaps on the smaller AMC's?

Yes Dave, everything for disc brakes from a Concord will bolt right up
to your 62 Classic except the booster. You might be able to use the
booster, but it will take some modification. The Concord booster mounts
directly to the firewall, the 62 booster uses an offset bracket that
raises it up 2-3". If the Concord booster is on a tilted bracket you may
be able to cut a new pushrod hole and drill new mount holes and use it.
I don't recall if there is room on the firewall in the 62 to do that,
but a fellow mounted one successfully in a 66 model. 

The Mustang II kits supposedly work, but the offset of the calipers is
different. I haven't mounted one myself, but have got the info from a
reliable source. The MII wheel flange is about 3/4" further outboard
than AMC hubs. So the track in front is increased 1.5". No big deal. The
calipers will have to be shimmed out to center over the rotors at best,
but I'm not sure the MII calipers will fit the AMC disc mounts. You may
have to have custom mounting plates made from 3/8" thick steel plate, or
at least an adapter to bolt between the AMC mount and MII caliper. The
AMC stuff bolts right on. All AMC disc brakes are around 11" -- 10.83"
or something like that for the later models.

I don't think I'd pay $175 for the works unless the rotors are useable
as is or after turning, especially since new rotors will be around $75
each. The master cylinder is cheap enough as a rebuilt, and as you
mentioned the calipers. You might not be able to use the booster. I know
you want to collect parts while you can, but if there is a chance at
finding an AMC in a local salvage yard when you get back you only need
the spindle, caliper mount, and caliper frame ) if you're buying new
rotors. The frame is the piece between the mount and piston body -- when
you get rebuilt calipers you just get the sliding piston body, not the
frame it slides in -- on big three cars the "frame" is usually made onto
the steering knuckle/spindle unit.

The XJ hoses only work on 82-83 calipers. Those are the same as XJs and
use a GM caliper. The earlier models use a Bendix/Ford style caliper
which uses a different size hose fitting. For those mid 80s Ford EXP
banjo hoses/bolts work (I don't think the normal Escort had banjo
hoses?). I bought a set of 82 hoses thinking they'd fit my 80 calipers
-- they didn't! You can also buy a brass "brake T" with one male and two
female fittings and use the regular brake hoses. I'm running that setup
now. The male end goes in the caliper, the hose in one of the female
fittings, and a plug in the other. That makes a nice 90* fitting. Copper
sealing washers (sold where the T is found) will likely be needed. I
used one washer under one of the fittings, two under the other to get
the fittings turned the right way and still tight and leak proof. No
leaks after four years. A third alternative is to buy 71-74 AMC disc
brake hoses. These have a 2-3" metal line near the caliper that can be
bent to clear the spindle, just be careful not to crimp the line when
bending. The reason for all these hose gyrations is that the steering
knuckle is shaped so that it interferes with the hose coming straight
out of the caliper. The 71-74 (maybe 75 -- K-H brakes) hoses use the
metal end to get around redesigning the steering knuckle. Around 75-76
the knuckle was redesigned. 66-70 hoses might be what I'm thinking about
though -- I believe they have a metal end also. Hopefully someone can
confirm which years used the 2-3" metal end -- I don't have access ot
any reference meterial. 

You can swap calipers from in front of the wheel to behind the wheel
also. As John stated, as long as the bleeder is on top it doesn't
matter. Just swap the mounts and calipers from side to side. You may
have to trim the dust cover for clearance. Concord brakes are usually
mounted to the rear, but I had to mount them to the front in my 63
American for clearance. Drove that car 8-10 years with the brakes
mounted that way!

It's been a while since I bought a setup, and when I did last it was
from a pick-n-pull type yard. Makes a big difference in price. With
rarity comes higher parts prices -- to bad higher car values don't go up
with the parts!! Or is it...

" would that $175 for that whole set up be worth it or would i be just
as well
off to go with the mustang II kit?

i agree with tom and john - that's a good deal and -much- closer to a
straight bolt on than the mustang kit would ever be, only a little
tinkering to make things fit.

" " so........ 1978 Ambo spindles won't bolt into a '55 Ambo ? "

I think so. The trunnion suspension was introduced in 1950 on the
Rambler, and migrated to the big cars in 53 or 54. I don't know if the
big cars, turnnion or king pin, used the same spindle bolt pattern or
not. After the big cars were dropped all AMC Ramblers did, so I think it
reasonable to assume that the big Nashes, at least those with the
trunnion suspension, used the same spindle bolt pattern also.
