Charlie, have you considered getting a brake cable for a Harley. I have
used those and they are beefier. Bob Hawkes

Hi Keith,
I think it's the cable. Compared the factory original on my '69 (still
in good shape after 36 yrs.!!!) to the new one. Those available now are
noticably less robustly constructed - inner cable has less strands,
smaller diameter and doesn't appear as tightly "woven". The outer
cable's metal spiral is round wire vs. the o.e. square section wire and
is smaller diameter as well. To be satisfied, I might have to make my
own. Need to make some Falcone cables anyway. Cheers,

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?

position they came off (the same as my '69's). Seems like the
inner

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.
