sure it wasnt the ABS?

[KillerCOM]

yea i'm sure...

there's no vacuum brake booster, no lines going to and from the power steering pump. it did have a separate electric pump with a high pressure feed line and a low pressure return. it also had a nitrogen charged accumulator like a normal hydro-boost.

it did have abs and i have worked on a lot of vehicles. they use this setup on some medium duty trucks. one of the international porta-john trucks at work have this setup.

I guess it's too late for pics?

The jeep is gone but the hydro-boost is back home in Virginia. my dad might be able to send me pics if not it'll have to wait till i go home, and i have know idea when that will be.

Never seen that. I have seen electric/hydraulic trailer brakes, and the GMC C6500 box truck at work has an electric/hydraulic parking brake. That parking brake is a piece of crap, though.

 

BTW, anyone want to buy a 24' box truck from Ohio? $8K takes it.

nope, but this setup is most likely to go in my other 89 manche project....
