Re: installing power brakes on a cj?
I agree totally.
I have seen 3 bad out of the box masters recently. The company selling
them then changed brands. The different brand seems to be better.
Still a rebuilt in a box with a warranty is sure as ---- better than a
used of unknown wear one that needs to be 'jury rigged' to 'work'.
The pads I have in now are the long life ones and the grabbing power
difference is noticeable big time because I am turning 33's. My friend
with manual brakes and cheap shoes can stop way faster than me!
On my next change I am going back to the cheap ones for sure. I can
return the long warranty ones and the store will give me a credit and
the new cheap pads free. Nice outfit. I just did that with some
expensive Heavy Duty 'lifetime' u-joints, got 2 cheap ones with grease
fittings and a credit towards my next purchase.

Re: installing power brakes on a cj?
It might work just fine, I don't know 100% for sure either way.
I just know that the master is designed to put out a certain volume of
fluid at a certain pressure to match the volume in the sump behind the
caliper and rear cylinders.
If it is too low, then the brakes might not grab as hard which can mean
a longer stopping distance. The pistons in the caliper can be different
sizes which makes the volume of fluid needed from the master a lot
different to get the same end pressure.
When I see all the sellers saying the same thing almost exactly that
they 'can' be made to work on a CJ7, that sets off alarm bells in my
head.
Sorry, but I tend to try and be honest with my opinions and err on the
cautious side and have them right more times than not. I can easily be
wrong too.
If the booster is the same, then just putting a proper master and
combination valve for a CJ on it should be really easy. I have no
issues with something like that. It is the different masters and combo
valves I have issue with.
Oh, just below your carb on the drivers side should be a large brass
plug. This comes out and the brake booster line threads in there.

Re: installing power brakes on a cj?
It might work just fine, I don't know 100% for sure either way.
I just know that the master is designed to put out a certain volume of
fluid at a certain pressure to match the volume in the sump behind the
caliper and rear cylinders.
If it is too low, then the brakes might not grab as hard which can mean
a longer stopping distance. The pistons in the caliper can be different
sizes which makes the volume of fluid needed from the master a lot
different to get the same end pressure.
When I see all the sellers saying the same thing almost exactly that
they 'can' be made to work on a CJ7, that sets off alarm bells in my
head.
Sorry, but I tend to try and be honest with my opinions and err on the
cautious side and have them right more times than not. I can easily be
wrong too.
If the booster is the same, then just putting a proper master and
combination valve for a CJ on it should be really easy. I have no
issues with something like that. It is the different masters and combo
valves I have issue with.
Oh, just below your carb on the drivers side should be a large brass
plug. This comes out and the brake booster line threads in there.

I just know that the master is designed to put out a certain volume of
fluid at a certain pressure to match the volume in the sump behind the
caliper and rear cylinders.
If it is too low, then the brakes might not grab as hard which can mean
a longer stopping distance. The pistons in the caliper can be different
sizes which makes the volume of fluid needed from the master a lot
different to get the same end pressure.
When I see all the sellers saying the same thing almost exactly that
they 'can' be made to work on a CJ7, that sets off alarm bells in my
head.
Sorry, but I tend to try and be honest with my opinions and err on the
cautious side and have them right more times than not. I can easily be
wrong too.
If the booster is the same, then just putting a proper master and
combination valve for a CJ on it should be really easy. I have no
issues with something like that. It is the different masters and combo
valves I have issue with.
Oh, just below your carb on the drivers side should be a large brass
plug. This comes out and the brake booster line threads in there.

hi carmine,
not sure who you are talking to, but they have no idea what they are telling
you.
I have since 1987 sold well over 800 boosters not to mention installing well
over 200 unto customers cj model jeeps.
it will fit, and will work well.

emailed that are selling wrangler boosters on ebay
hi carmine,
not sure who you are talking to, but they have no idea what they are telling
you.
I have since 1987 sold well over 800 boosters not to mention installing well
over 200 unto customers cj model jeeps.
