Today at the GMCWS rally in Auburn Chuck Aulgur and Rick Flanagan gave a presentation on the "reaction arm" braking system that they designed and developed for the GMC. I believe that Chuck is the inventor and initial designer and engineer and then Rick made changes that make it manufacturable.
After the presentation anyone who wanted to was allowed to drive Rick's coach which is one of only 4 coaches with the system installed. We went for a ride around Auburn and were encouraged to get the coach up to speed and then stop as fast as we could. I would have to say Rick's coach stopped as easily and quickly as a car. A panic stop at 35 mph and up made virtually no skidding noise. If any tires made noise it was the front and not the back.
Steve Ferguson said that the coach stopped better than his 2010 pickup truck and called this the best single improvement in the GMC motorhome since its inception.
Thanks to Rick for letting me drive it - amazing and on my list of future enhancements for my coach.

Netters,
With no reservations I must add that I think that there has been no
other improvement or device made since production of the GMC that
ranks even close to Chuck Aulgur's reaction arm system. I have seen
and heard the presentation twice before and it does not do the device
justice. Once Chuck starts speaking like a rocket scientist, he
loses nearly everyone in the audience and I think that has been the
problem. Rick Flannigan did the CAD reverse engineering on Chucks
device to simplify manufacturing of the parts and has one of the four
units out there installed on his coach. No matter how hard Chuck
worked to explain how the device worked, no lights came on until the
rubber hit the road. To simplify the explanation, Chuck's reaction
arm harnesses the energy that causes weight transfer, or the braking
action that causes the rearl of the coach to lift, when the brakes are
applied in ALL situations and in every braking application. Word
spread quickly once a few of us rode in, or drove Rick's coach and got
to try the device through town, then out on the freeway on flats,
hills, and stop and go traffic.
I still can't believe how incredible and controllable the coach's
brakes were. After just two stops, it felt as though I had been
driving it for years. I have 9 vehicles registered and on the road and
none of them brake as well and as predicable as Rick's coach. Stop
after stop, mile after mile, those brakes stopped as well and as
consistantly as they did at the first stop sign out of the park.
Armand quoted me correctly when he said that I reported that even my
new 2010 Chev pickup truck doesn't respond to braking action as well
as Rick's coach, neither does my '94 Caprice. If you've ever pulled a
towed with a tow car braking system installed and had to do a hard
stop, you were probably thankful for the toad's brakes. Well,
multiply that by two and you will just begin to understand how well
the reaction arm enhances the GMC brake system, with one exception, NO
nose dive, Nada, zip, none. Word spread quickly at the rally and by
the time dinner was served, about half of the attendees at this rally
either rode in the coach or test drove Rick's coach and all had the
same reaction. Every GMCer walked out the door shaking his head and
was smiling in amazement. No BS, just fact. You could have cooked
anything you wanted on Ricks Alcoas by the end of the day because of
the heat from the hundreds of braking applications but what is
significant about this statememt is that ALL wheels were within a few
degrees of each other meaning that each brake was doing the same
amount of work.
This is without a doubt, the single best innovation anyone has come
up with for the GMC in the history of the GMC. No matter what GMC
coach the future holds for me, this system is now at the top of the
list.
BTW, that bicycle gizmo was a mock up of the reaction arm complete
with gauges used to quantify the reaction forces that occur during a
typical brake application. I almost understood how it worked until
Chuck started explaining it to me :>)
I tell you, these rocket scientists...........

Steve,
It's great to hear some feedback. My expectations were great, and it sounds
as if they are exceeded. Wonderful!
One thing you didn't address that's important: What is the rest of Rick's
brake configuration? Without minimizing the importance of Chuck's design at
all, reaction forces are of little importance without good brakes.

Ken,
Sensatized booster, 6 disk system. It also uses a disk brake
application combination/prop valve. He also has a quadrabag system
but that is not necessary. This system will work with drum brakes but
the backing plates do not lend themselves to the easy to make brackets
that the disk brakes do. It is doable (that was one of the questions)
if you make the adapter. Not a whole lot to this thing at first
glance but it is very well engineered. If the bracket for the arm
brakes, you do not lose your brakes and you can continue your journey.
Of the systems out there, no one has broken one so far. It
free-floats and any more information than that and you'll have to find
access to the CAD drawings yourself.
We are so lucky to have antiques with this kind of support and these
kind of improvements being invented.

Wow! I too drove Rick's coach. As was said earlier, until the rubber hits the road, you don't get it. It stops just like a car. No need to shift down on steep downgrades and tax your transmission. You've got 6 wheel disks doing their job, not just 3 1/2 wheels braking as in the present setup when the backs lock up.
Jim Kanomata is selling the setup, so you can get quotes on the system from him. Preliminary parts estimates (which included converting all four back wheels to disks) were in the $4000 ballpark according to him. Jim estimated installation labor around 10 to 12 hours.
It really isn't practical to install the system on drum brakes according to Chuck. Developing a mounting plate to mount the system on a drum brake backing plate is difficult because of the lack of a flat surface to mount the hardware. I doubt you'll see this combo.

Ken,
IIRC from when Chuck presented the system at Pueblo he noted that you needed

No I don't Ken. Give Jim a call as he's the investor behind this.
Seems like I recall it's the Eldo disks that so many are already
using. 80mm fronts, EBC yellow stuff pads. If you already have the 6
wheel disks and sensetized booster, you are way ahead of the game.
For those with the Powermaster setup, the reservoir is more than up to
it.

This is interesting. Couldn't follow Chuck's explanation the times he's posted it on here. I'm not that smart. Fortunately I can certainly understand people telling me it works from experiences. I guess you can put a price on good brakes. One of these days I'll have to figure out how to afford it.

Jeremy,
BMW has an option for motorcycles that does the same thing. It was
called an Earl's Fork back in 1949, I don't know what they call it
now. It is basically the same though. The harder you apply the front
brakes, the more the front end rises. The reaction arm works on the
same principle and after hours of hard stops and stop and go driving,
the rear Alcoas are actually slightly warmer than the fronts. (This
is contrary to what I posted earlier.)
Part of Charles presentation is his explanation of why the GMC really
only has three wheel braking. Two fronts and half each on the two fwd
rears. You put those rears to work and the difference is just plain
unbelievable.

Oooh post here! I'm guessing there are a bunch of us who want to
know, though we'll not be able to afford it for some time.

Floating calipers are really nothing new. I have a book called (amazingly) 'Brake systems' by HP books Copyright 1998. They talk about floating calipers, how to adjust them to change tire loading effects. They are common on dirt trackers and sprint cars. Where they are used to modify cornering during braking and to control pinion angle changes.
It's an obvious solution once the problem is determined. I'm too new to the GMC to know if the rear tire skidding was an understood problem or not, but the realization that the center axle lifts the coach was definitely a ground breaking insight.
This issue isn't a problem on single axle systems as who cares if the axle rotates a little during braking...
So the floating caliper is a well understood solution to brake torque jacking. And is a perfect solution to the problem.
Oh and to answer a question no one has asked, yet; Yes, you should run floaters on both axles. If you only run them on the front, the rear will still lift reducing traction on the rear axles.
Of course the whole backwards trailing arm on the front axle is the real problem and certainly causes more handling issues than just braking!

Phil,
Data sheets were passed out at the seminar.
Larry,
The unit can be ordered to work with the True track unit.
Reaction Arm System will not do anything to keep the boggie arms from
moving laterally.
I have over 4,000 miles on my reaction arm system with majority miles
pulling the Olds Mini van with total weight of 6,000 lbs.
I'm a true Ornamental driver; all gas or all brake.
