Brake upgrade #3...

Randy, what's the part number for the item in the bag on the far right? (Looks like two lines and some kind of bracket)

Do you have a part # for the booster to firewall adapter bracket that you re-used from a previous setup?

Thanks!

Bag of goodies is the prop valve bracket and lines. Disc/drum. http://www.summitracing.com/parts/tff-2302nb/overview/

This should be the booster mount/pedal bracket. http://www.amazon.com/MBM-MBM-J7486...1461382587&sr=1-7&keywords=CJ+booster+bracket

I think I'm good then on the first part. I did, however, order the one for a disk/disk setup, which is what I'm running.
On the booster bracket, I ordered this one after talking with a guy at Summit. We'll find out tomorrow as that's when it should all be delivered. Got an event this coming weekend and need the 8 in the trailer Thursday morning. Time will tell. Goal is to have the old out of the Jeep this evening, in the morning so that I can do a quick test fit once the parts arrive tomorrow and if there are issues on the bracket, I guess order the one you posted here from Amazon, maybe an overnight ship.

Thanks for your help, Randy!
 
No problem. I saw that one at Summit, it just didn't look right, but it might be the picture. Hope all works out well- I towed a heavy trailer today and the brakes stopped great.
 
Alrighty, Randy. Parts all came in today.
In doing some hold-parts-up-and-eyeball-them-with-existing-parts moves....got some questions.
Namely, the threaded shaft coming out of the end of the booster that would point towards the firewall....it's threaded.
One on the existing one is not and is cross drilled for the pin to go through it. I see no instructions.
Am I gonna need to unthread the existing one from the old booster and thread it in the new one in it's place?

Also, the proportioning valve....what happens to the old one down on the frame behind the clutch linkage? Gone from the equation and plumb new lines into the new one adjacent to the new master cylinder?

Thanks in advance!
 
Question 1: Yes, I had to unthread the old rod and thread it on the new booster. You may have to shorten the threaded rod some.

Question 2: Yes, I got rid of the frame mounted valve. I suppose you could use the new valve in the stock frame position, but I don't know if the lines would match up. There are inverted flare coupler fittings available for joining brake line sections.

There are inverted flare coupler fittings available for joining brake line sections. Now I'm really being a pain.....got a link? :crazy:

My subsequent (yes more :banghead:) questions in blue.
 
When I did mine I got a 2 1/4" coupling (for threaded rod) and I had a cevis (threaded). I screwed the coupling onto the threaded rod, then I screwed a 2 1/4" rod into the other end of the coupling (was a 2 1/2" bolt I cut the head off). I then screwed a female threaded clevis I had from another brake. This made it adjustable. If you don't have the parts you can get this kit which is made for the booster you have and will get you on your way. http://www.summitracing.com/parts/tff-4750
 
Since I was replacing a brake/booster set up that I bought for the cj8 build (one I used was defective) I already had the valve installed on the frame so I didn't buy the valve that you guys bought.
 
Great! Thanks, Randy and Jammer1.

Only other thing I've got to sort out it would appear is the bracket I ordered between the booster and firewall. It's just not right. The spacing between side plates and the bolts in the back of the booster don't jive. I don't thing I should modify it but find another one or see if the one in the Jeep currently will work. I ran out of time before Southern 4wd Associations annual Trailfest (this weekend) so it'll go on the trailer as is and be my "booth babe" as I represent CartoTracks for the next 4 days. I'll tear back into it next week. All of this research is helping me tremendously. Thanks guys.
 
How much room is between your booster and steering shaft? I just saw where tuff stuff makes an 11” double diaphragm booster. And I am hoping it would fit. Or maybe a better question is how wide is a 9” booster really measure.
