Same experience here. Plus I've found myself in a number of
situations in my Bronco, with a dead engine, wondering weather I should
let up on the brakes to start a down hill decent, knowing that every
time I release, I use half the storage vacuum, and at six times there
will be NO brakes. Remember that Dodge wagon coming off a hill without
brakes, in terrain much like the Moab sandstone.

no Lee I have not made funeral arraignments. but I do live on the top of a
hill from a school and when I work on my jeep I like to drink allot of beer
and oh yea my emergency brake cables are rusted and don't work, you know
those old jeeps. and my jeep has a supercharger 454 in it so I always have
the throttle wide open so I don't use brakes that much. but I hope
everything will be o.k.
but seriously I called the guy who sold me the booster and he said it is
off of a 94 wrangler with a 4 liter 6 cyl. I would think that if I keep the
same master cylinder and proportioning valve that the front to back
difference in pressure would stay the same and I would be increasing the
pressure with the booster. just because they changed the part don't mean it
wont work maybe they were just looking for a different pedal pressure. has
anyone done a CJ to wrangler brake conversion? thanks carmine

In 91, the AMC designed Jeep disappeared.

Chrysler took them over and changed a whole mess of stuff including the
brakes.

They changed the calipers, the master, the combination valve, etc....

A 94 master will 'NOT' work on a CJ7, period.

I just called my local parts store and asked them the price for an 86
CJ7's power brake master cylinder.

It costs $53.00 minus a $15.00 rebate for the old one.
$38.00!!!!!!!!!!! In Canadian dollars even.....

I for one sure the hell won't risk my life over forty bucks!

Buy the right parts please.
