Hey Charlie,

I had the same exact problem a few weeks ago with the brake cable.
Installed a new one with the switch and with max slack, the darn brake
was locked solid on the wheel, wheel would not budge. I did what Greg
mentioned, removed the arm and moved it a tooth on the spline, was my
only choice. Now I am near the other side of the spectrum in that there
was too much cable to tighten up/adjust, but I've got it set and have
some room to work with as the pads where down. And yes, this cable does
feel spongy, though the prior cable had no switch and I could pull the
handle to the grip. Same happens now when pulling hard, but I have not
had her on the road yet to test them out, so I'm hoping she'll stop OK.
I don't remember the 71 Ambo having spongy front brakes, I thought it
had a pretty firm handle, not sure what causes one to be nice and firm,
another to be spongy. If you figure it out, let me know.

Tried that already. Then, even with all of the slack adjusted out, the
lever comes all the way back to the grip with very little actual
pressure on the shoes. Thanks,

Pull off the brake actuating arms and rotate them one spline so that
the end of the arm is closer to the cable lug.

 Thanks Pat. Thought about that as a last resort. May try another cable
first (maybe the factory original cable still on the '69). This is the
first cable I've had with the switch in it - are they all rather
spongey
feeling? Or is it more the cable construction?

slack adjusted in, the brakes drag. Cable was fully seated in both
adjusters and switch, the levers (on the backing plate) are in the
same
position they came off (the same as my '69's). Seems like the inner
cable is too short or outer is too long. Any ideas?

I've seen some problems like this in the past. Carefully peel back
the
end of the outer cable, maybe even pull off the end ferrule if you
can.
If you work slowly and carefully with a Dremel tool and a thin, red
cutoff wheel, you can cut off 1/8" or so of the outer spiral housing
and

thus build some slack into the system. You have to be VERY slow and
careful not to nick the inner cable. There will be lots of abrassive
dust from the project, so inject some cleaner and blow it out with air
from the opposite end to flush the debris.
