who knows something about these? they seem expensive, but have 3 times the braking pressure. :woot:
-
I've had them in my last two 3/4 ton trucks, they are amazing. Chevy uses them since the early 2000's (perhaps earlier but i didnt own that era truck).
do you find its too much pushing to make your new jeep stop?

My old 350 ford pickup had it, my cobra had it and my 2500 gmc pickup had it. Loved it in everything except the gmc but that system had a leak we couldn't trace down. But the 2 ford systems I had was awesome. My only complaint was if you lost your power steering you also lost your brakes. Normally not a big deal but I blew a ps pump towing on my way home from Maine once and that made for a scary ride the last few miles. Till I could stop and fix the problem. But otherwise I loved it.

Most if not all diesels run Hydro brakes, also engines with very big or agressive cams will benefit from hyrdaulic master since it doesn't draw a vacumn. GM trucks have used this system on diesels dating back to the early 80's. Depending on the vehicle, a system can be pieced together quite easily. What are you thinking of putting this on?

The international (ford) 7.3L I had was vacuum assist and used a belt driven vac pump, I'm not sure if that changed in the later years.

I think I have a few Chevy hydro boost setups if you need one, the only thing I can add to this is if your belt breaks you loose your power brakes all together I've had it happen

Electric power steering pump!

yea, the cj brakes could stop better. front discs chevy 44 1/2 ton, rear drums ford 9". maybe just add discs in the rear.

Do you know what master you are running. I'm following dookey's revenge on pirate and I know he just swapped in a Dakota master to help with his braking.
-
im not sure, have to look, but i think its cj

I was unaware of that Bobby, thanks for laying down the klnowledge.

This is what I am thinking, When I swapped to the D44's, my stock YJ master couldn't stop worth a dick. I went with a 1986 E350 Master, very little modifications to get it to bolt in (little bit of grinding on te emounting ears to clear the booster) and it would stop better than stock once I got a master that could supply enough volumn for the larger calipers.
Another option is to pull the master off and check length of engagement on the plunger as it enters the master. should be adjustable on the end with a set screw. but I am more or less thinking that the stock CJ master simply will not supply the volumn needed for those calipers. Also if you add disc rears, I found that a 2psi residual pressure valve really helped with maintaining a good pedal at all times.

Once you're done figuring this out I'll do the same swap bob :-)
*edit - Jerry what master is in your jeep? It stops well without a booster at all.

Yup, my 1996 7.3 has a vacuum pump for the brakes and HVAC controls.

I'm pretty sure mine is from a mid eighties grand waggy.

I have a mid eighties waggie. Buy it bob.
