Jim,

I agree with what you've noted below.

Double Trouble has 80mm calipers on the front, 60 mm Caddy calipers on the middle wheels, and new OEM drums on the rear all with
carbon metallic pads. It also has a P-30, brass combination valve, stainless steel brake lines, stainless steel flex lines,
sensitized booster and it stops REAL GOOD too!

I am an extremely defensive driver from the lessons I've learned by riding motorcycles for 50 years.

I am of the opinion that the situation you describe below could have minimized or maybe even prevented by following the rule we were
taught back when we got our driving licenses in the Stone Age; leave one car length for each 10 mph you're traveling. When some one
pulls into my "safety zone" I slow down and reestablish that distance. I may not meet that requirement 100% of the time but I have
never run into a situation like the one below.

When I approach an on ramp on a freeway I move out of the right lane (learned that from watching truckers) to avoid some idiot
towing a loooong trailer full of rolled up hay bales flying down the ramp and never even looking to see if anyone was in the right
lane!

I agree there is very little one can do to prevent colliding with some idiot that runs a stop sign, a red light, or just comes out
of "nowhere." In those situations the reaction arm system rules.

I was talking to Manny about his reaction arm system when he was first developing it and HE agreed with me that it wouldn't do much
unless you were in a panic stop situation.

I will make one comment about the legal aspects of modifying the brakes which is not relevant to the USA as I live in Australia.
Here ANY modification to the brakes of a vehicle would have to be certified by an engineer approved and certified to do so. If the
accident was investigated and it was discovered that you had modified your brakes without that certification your liability
insurance (issued by the state government) would be canceled.

To those of you who say; "how would they be able to tell?" I'd like to point out that most of the rear brake systems that convert
from drums to disks are made with flat plate steel brackets, one look at those parts and an automotive engineer would KNOW in an
instant that Detroit never made caliper mounts that looked like that. The only one that you could possibly get away with would be
the OEM Caddy setup.

Well, I have a comment on the plus side of this discussion. A few weeks ago
I got a phone call from a customer that I installed a 6 wheel disc brake
system for. He was driving in Portland, Oregon moderately heavy traffic at
freeway speeds with his GMC when some idiot pranged the guard rail and spun
to a stop crosswise in traffic. All traffic immediately took all kinds of
evasive action, swerving into lanes occupied by other vehicles, full battle
rattle emergency lockup braking, etc. Well, my customer in his GMC with 6
wheel disc brakes, P-30 MC, all disc distribution valve, cadillac rear
calipers with cable e brakes, jumped on the whoa pedal, and just stopped
safely without hitting anything. Only damage was slightly soiled underwear.
After he stopped shaking and got to a stopping point, he called me to
discuss how well his coach had done, and to thank me for the upgrades. He
said that with the stock braking system, he knows without doubt that he
would have had a different hood ornament on his GMC. I know all the
arguments for keeping the old girls stock, but these braking systems are
night and day improvement over the stock drum brakes. Plus there is an
added bonus, just a quick glance will tell you the condition of the pads
and rotors. When is the last time you removed your rear drums and checked
how much brake lining you had left? Just my take on it. Add the reaction
arm system and you better nail everything inside your coach down, because
it is just that much better. Your opinions will vary on this and I applaud
them and welcome them. Just do not defend OEM systems for their
superiority, because that clearly are not.
