Been there done that, well only in snowy, slippery parking lots <lol>. The
brake peddle bucks and kicks under my foot and you can hear the system making a
grr grr grr sound. Other tests I've done are 4 low, 20+ mph, jam on the
brakes. The system cycles until I get down to some low speed and then the tires
lock and I grind to a halt. I don't know what the exact speed is when the
brakes lock, but I'd guess that its between 10 and 5 mph. Braking distance is
about the same as when I pump the brakes.
IMHO ABS isn't really of much use on the dry, or for that mater for most
drivers. I read somewhere that most drivers simply jam on the brakes and drive
straight into the obstacle rather than braking and steering around the problem.
And for those drivers ABS is truely a bad thing because it increases braking
distances. Unfortunately there are those out there that don't know how to drive
and all the ABS/non ABS in the world isn't going to make a bit of difference for
them.
But, anybody can disable any ABS system simply by pumping the brakes. They had
a big advertising campaign here a couple of years ago telling people to not pump
the brakes on ABS equipped cars in slippery conditions. These guys that are
rolling down hills with the ABS cycling (and I don't believe they are driving
Jeeps that are in proper running order) simply need to lift their foot and put
it down again, repeat. I know that is easier said than done, cause I had that
rolling downhill experience with my GMC.
Personally I use ABS as an early warning system on the slippery. Sometimes it
is hard to tell if the roads are just wet or if they are icy. If I brake and
it cycles I am clearly going too fast and need to slow down. And if I ever need
to brake and steer around a problem it is one less thing to pay attention to.
Basically I've delegated the emergency braking to the computer. However,
delegation does not mean abdication, yah still gotta drive. <lol>

I have just spotted for the poor suckers.....
It 'really' hurts my feelings when someone I am spotting for just calmly
drives into the freaking tree!
100% for 'sure' his front wheels were turning right up to the end!
He then did the same run a second time with the relays pulled. Bingo,
he could stop before hitting the tree and do the 3 point turn around the
corner.
He did this two different days with the same results. Same deal for
another TJ out with us.
There is one other spot where the TJ's go totally out of control and the
spotter better be off to the side or they will get run over because
there is no way that Jeep is stopping until it hits bottom.
I can't comment as to why your aftermarket ABS doesn't work the same as
the GM's or the stock TJ's though as you imply below.....

100% for 'sure' his front wheels were turning right up to the end!
He then did the same run a second time with the relays pulled. Bingo,
he could stop before hitting the tree and do the 3 point turn around the
corner.
He did this two different days with the same results. Same deal for
another TJ out with us.
There is one other spot where the TJ's go totally out of control and the
spotter better be off to the side or they will get run over because
there is no way that Jeep is stopping until it hits bottom.
I can't comment as to why your aftermarket ABS doesn't work the same as
the GM's or the stock TJ's though as you imply below.....

No I don't own one, I just have spotted for them on the trail.
It 'really' hurts my feelings when someone I am spotting for just calmly

100% for 'sure' his front wheels were turning right up to the end!
He then did the same run a second time with the relays pulled. Bingo,

I have never trusted ABS off road since and do not recommend it for 4x4
use. If I or anyone needs the extra control of 4x4 driving, they need
braking control too.

It 'really' hurts my feelings when someone I am spotting for just calmly
drives into the freaking tree!
100% for 'sure' his front wheels were turning right up to the end!
He then did the same run a second time with the relays pulled. Bingo,
he could stop before hitting the tree and do the 3 point turn around the
corner.
I have never trusted ABS off road since and do not recommend it for 4x4
use. If I or anyone needs the extra control of 4x4 driving, they need
braking control too.

Re: ABS vs Part-Time 4x4 ?
And if I had ABS I'd disable it when pulling my boat/trailer ... geez ...
I'd be clicking my way through every stop sign/light I encountered.
