Denis,
Reproductions of 57, 58 & 59 brake boosters are
available from a company called Karps out of Upland, California.
This company went to enormous trouble to replicate these otherwise
completely unobtainable to find parts a few years ago. Chrysler
300s from this era also use them and their owners created a demand for the
part, thank goodness. I bought one a few years ago. The price
was very reasonable and the part itself is phenomenally good. (I am
one very cheap guy, and usually feel entitled to complain if any
part isn't sent to me just about free and installed at their expense,
too.) I cannot recommend Karps highly enough.
Here is a link to their site:
They will offer to install the new part for you. If
I was you, I'd let them. You will have to send your old booster to
them by UPS unless you are close enough to drive it there. I have
replaced it myself but it is a lot of work. You'd be surprised how
many fiddly little parts are in the booster. You'll need to completely
remove the booster. There are eight bolts holding it on and you
know they are hard to get to. In the course of this
procedure, you will have to remove the master cylinder. Be prepared
for some issues with bleeding the system when you re-install it. In my
experience, it is next to impossible to power bleed a 1958 with the original
MC, although some people have suggested some ingenious ways to do it.
One way is to get a spare top for the MC - easier said than done in itself -
and drill a hole in it. You then get a hose of some sort and feed
fluid into it from a tank higher than the car, using gravity.
It all sounds very complicated and it is. I know you
are in California. If you are anywhere near this place and they agree
to do it, have it towed to them and let them do it. Getting the parts
off and then back on again is not for the faint of heart. Bleeding the
system is very, very difficult.
Warning. I'll run hotter than a
three dollar gun when someone who does not have a 57, 58 or 59 writes in to
this list and says I am overstating the case in their lousy,
inexperienced, stupid, opinion. Unless you have done this job on this
era of car, keep your, "I would think . . . " opinions to
yourself. I wish you would think before you run right into the
facts. Trust me, I won't be subtle.
The brakes on this era of car can work very well when they
are set up correctly and well maintained. Setting them up is not
easy. Your average brake shop hardly has the tools to get the rear
hubs off let alone bleed an almost impossible to access round topped single
pot master cylinder.
Denis, I've had the pleasure of communicating with you
before. I'm glad you are getting the roof fixed on your beautiful
car. I hope your partner is well and is able to go with you on your
trip. I'm glad you don't need it to be ready till August. You
can relax and find a place that can get the brakes done right.

(With more brake experience on this car than I care to
think about.)

Subject: IML: 1958 Brake
Bellows
Well, after two attempts to get the brake right on the 58, the
Bellows has a nasty leak in it. Are these still available, and where can I
get one? Perhaps the third time will be lucky? This car will be driven 850
miles down to Tucson in August or September.
