The original subject: Aggressive Braking "changed" to Math Question.
HI FOLKS,
As I said in an earlier post, I helped Jim K Develop the Manufacturing
process of the REAR BRAKE
DRUM CONTROL ARM SYSTEM which he now owns as well as the Patent which
has been applied for.
The "advertising" video uses "selected scenes" from many test stops at
45 MPH with and without the enhancement. Jim probably picked the
extremes to tell the story. At Amana, Iowa when we first unveiled the
System we showed video of 45 & 35 MPH stops as well as G-force plots.
Every one was interested in "wheel rotation", tire circumference, and
all the visual aspects of the testing.
Based on that experience Jim K and I elected to stay with the CRUDE
measurement of revolutions after wheel lock up as the output data. You
might say I was surprised at some of the comments over the past week.
Every audience is different so I pulled out the Amana presentation
that included G-force plots at 45 MPH and 35 MPH that were gathered
during early testing. These plots give us some very accurate data.
When the stop begins the G-force show us in seconds exactly when the
forces "go negative" and when the forces returns to "zero". Knowing
the time form these two points and the FPS that we traveled, the
distance to stop can be calculated. Negative G-force Intensity was
also captured.
WATCH THE REVISED VIDEO and I hope this helps all who are interested

When Jim K gets his " _ _ _ _" together he will have it on his site.

There are a lot of improvements in that new video. I will be anal enough to point out that the "estimated six rotations" after brake application at 45mph statement is way out of sync with the other claims though (since six revs is only about 46', which is back in "hitting a brick wall" territory, and the video clearly shows a lot more than six revs after the weight transfer starts).
Otherwise, the claims, facts and graphs seem to show a very realistic, impressive improvement in braking. Good work.

Thomas and Jim,
I've followed this thread from the beginning and what I read is not anyone questioning the effectiveness of the system but just a bunch of very analytical people wanting to do what they did for a living....that is making sure the numbers work.
In the fairly short time I've been a member here, I've become EXTREMELY impressed by the obvious intelligence and creativity of the members. A bunch of really, REALLY bright people on here. A far larger percentage than any other internet forum with which I've ever participated.
In thinking about this, it seems we have a larger than normal (from THE GENERAL population) population of retired engineers and mechanics and other hands on types. Most people who survive to retirement develop some wisdom (unless they are in politics) and the amount of seasons wisdom here is really impressive.
In other words, don't take the questions personal and keep up the good work.
