Hi All; Was wondering if anyone has installed an ABS brake system or was thinking of doing it? Pics. ? Thanks Doug

Sounds like a butt load of work for something that is marginally safer.
I know ABS has saved my hide once froma small fender bender...but put it in danger at least a dozen times.

Wouldn't that take a computer and speed sensors on all the wheels? Lots of work, and no computers on my truck!

Several years ago, I saw an ad (and maybe an article) on a "device" that attached to the master cylinder and was supposed to emulate ABS on a non-ABS vehicle brake system. I doubted the ability of the device, and I have not seen any references to it in several years.

My best guess is that it had some sort of pulsating output to limit braking and prevent wheel lock. However, I don't know how else it could do that and not cause an increase in stopping distance. The sensors on the wheels are there to tell the computer that a specific wheel has stopped/slowed in relation to the others. For that input, the computer then allows the brake to be released momentarily and therefore not lock, hopefully to prevent a skid.

I don't see an easy way to install an ABS system, short of mounting a 67-72 cab/body, on a late-model ABS chassis. In my opinion, if that is what you have as your goal (to have ABS), then you'd be bucks-up to use a late chassis. Anything less would be a monumental undertaking with a lot of unknown variables.

Again, my opinion.

Thanks for responding Fred & Longhornmail, with the some of the extensive mods and upgrades done on this board I thought someone would of done it by now. I just think it would take a "disc brake upgrade" to the next level, however time, money, and simplicity are all factors, later Doug

THIS IS ALL YOU NEED TOO MUCH WORK W/ ABS

I find ABS a pain in the ass, sure its good sometimes, but at low speeds when I need to stop on ice it don't work!

It don't stop you in loose gravel either.
