When I arrived home today I found Johnny and Stick happily at work, despite
the pouring rain, on the installation of Stick's Manny Brakes.

While saying "Hello" after having been gone to Sun'n'Fun, I got suckered
into the project, just a little. They were having a heck of a time getting
the hub apart after having removed the center wheel disc brakes installed a
LONG time ago by Bill Telgen (who was "Mr. Hydraulic Wiper Motor").

Needing a tool I didn't have, they went to find one and some lunch. Later,
I visited with them again, only to find them making no progress. My best
solution, after trying several, such as it was, involved an angle grinder,
wielded by Johnny.

Only after considerable damage was done to the hub fittings, I suddenly
realized that something just didn't look right and began asking questions
-- and getting no answers i could understand.

Finally turned out that those middle discs apparently came from Leigh
Harrison and have either entirely different than OEM, or seriously modified
OEM, hubs! The 13" or so discs he uses do not fit on the OEM hubs as do
the Cadillac discs we usually use.

PANIC TIME!!! Where can we get hubs & bearings?

Guess what: 3 cardboard boxes in my Sea-Land container were long ago
marked "Rear Hub". :-)

They look good and so do the several used sets of bearings I found, along
with the new pair of seals I bought from Dave Lenzi at Branson. Maybe
Stick's GMC won't be a permanent resident of my rack after all. Unless he
can't come up with my outrageous charge for those solid gold parts!

The moral of the story is, be SURE you know what you've got before you
start modifying so you can be sure you've got all the right parts. No way
for any supplier to anticipate your configuration.

Copies of this are going to Manny and Karen, so a caution will probably
appear in the manual eventually.
