There is much more to braking than just having the ability to skid
the tires if no ABS....if you do have ABS...to then initiate ABS,
which has many attributes other than just cycling MC PSI to keep
the tires from stopping or slowing down to skid
Modulation is my main requirement with a very close second of thermal
characteristics
OEM to mud hen friction materials can skid/ABS the tires and again there
is much more to it than just that
But, generally that is all folks think is it and all they want. Okay
too, as that is the expectations...but not mine. Mainly because
consider braking of higher importance over acceleration and ultimate
speed...though am still a boy racer that also loves it
Modulation and the shape of the braking curve go hand in hand.
I can out stop a similarly setup 1996 Suburban (GMT400's have poor
to bad brakes, but can be made to be good to almost great...another
but it takes constant tuning) because I don't allow my Sub to go into
ABS...unless I've gotten into a situation where I've no other choice
than to nail it to the floor
Real experience, as going through an intersection one morning while
the pavement was wet from early dew...a Land Rover jumped his stop
sign thinking I also had one...nailed the brakes to find that the
pavement could not support that kind of braking. So ABS kicked in
and seemed like accelerated, but know just stopped decel and continued
at whatever speed (under 20MPH by that time...was going 25MPH)
Hit (glancing) that guy and almost ran into the Honda on the other
side of the intersection.
ABS initiation has 'less' braking than the point just before ABS
turns on. That is where I modulate it to be, or try to
Without properly bedding in 'my' brakes, their braking curve looks
way different. Haven't, nor the instrumentation to do so, but know
how it looks via the feel because did purposely NOT bed in a set
of proto-types tested for a buddy. Other set did bed in
Learned much on that in an oblique way while still in college and
working part time as a designer in a Industrial controls company
Was assigned to design to a DOT specification for a tire test stand.
One of the first solid state (up till then, they had hydraulic)
dynamometer's for this
We were 2nd contractor to the dynamometer builder, we did the controls
and electric motors
Tires of old also have a similar break in vs performance. Tires today
do not as much, but they still have 'some' break in requirements or
attributes
With all that, goes back to a previous comment that bedding in is
for the purist of braking or high performance
So, just understand that there is a difference, but then maybe most
folks won't bother nor notice the difference...
