anybody have experince with hydrovac brakes?

Anybody? I need help with my truck. My experience is with air brakes. Not this old ass shit.

what is it? i know air brakes and standard brakes ive never heard of them

It’s on a 1941 GMC CCKW. It has a master cylinder under the cab and has a hydrovac unit on the frame rail behiend the cab. It has two valves in it to take vacuum from the motor and vent it. it also has a tank to build pressure in. It’s to have increased line pressure to stop the truck being that it weighs 10,000 lbs.

do you mean hydrobooster setup?

ooh no thats is diffirent lol, not sure on that setup hmm.

never even heard if it is it hydrolic or air? or both

Lol deff not a hydroboost.

It’s hydro. I need some old school truck peeps in hur.
