While reading through your thread I noticed this post. I also would be happy with stock power, but I could not help but daydream about more power. I had a brief idea of building a QT Cherokee into a classic version of a Grand Cherokee Trackhawk. I noticed that my 78 Cherokee, as equipped, weighs in at about 900 pounds less than a brand new Trackhawk. It would be fun to have an old Cherokee stomp the shiny new toys that Jeep puts out today. Especially since people think older vehicles are too heavy. I decided that my 40+-year-old QT would not be able to handle the 700 hp that would be required.
My carcaine addiction wasted my life but it is a life well wasted.

Help! Brakes .. UGH

My last big issue is packaging some sort of brake system in this space. There is not enough room to the valve cover, not even close for a 7" booster.


I was figuring hydraboost.. BUT - it seems all the systems have the accumulator on the INBOARD side. Well, that's where I need the space. Uh oh...

So I found some bell crank units that offset the vacuum booster to the outside... that might work?
Are our Jeep brakes based on a GM system? I think so.
Trying to figure out bolt mounting patterns and the like has not been easy.

THEN - I found a hydraboost system made by CPP. It has the accumulator on the outside... Even then it's going to be close, and I'll have to relocate the oil dipstick it looks like.

It includes a master cylinder and an adjustable prop valve attached below the booster. I was going to move the original prop valve anyway, so this might be a good choice.
Excited, but can't find much in the way of info on the mounting dimensions... That's very disappointing.

So - after 2 weeks of thought.. I ordered it from Summit tonight. I am pretty sure it is based on GM stuff.

So again, does anybody know if our brakes are GM based?
It's not yours 'til ya bleed on it . . .

Can't answer the GM question but I read you could run the HB upside down putting the accumulator high on the other side. I was going to do it until I decided to go to a hydraulic clutch. It would've interfered with the clutch master.

This was to get it away from the turbocharger. It didn't touch since I had already moved the M/C to the other side of the brake pedal but I wanted it away from the heat.

I run mine upside down Jim. It's an Astro Van booster with the bracket to fit our rigs. That said, my pedal is so high, my knee hits the steering wheel sometimes.

1974 Cherokee S. It's driving but needs more work. As usual!
