Re: Caddy Brake Booster Swap???

Hey, I just did something very similar not too long ago. Used a booster and master from an '85 vette. I'm mailing you the info now.

Late model caddies use smaller boosters than the corvettes, and there are a lot more of them in the junk yards.
You can still mount the pickup truck master cylinder on the booster if you want too, depending on brake wheel cylinders volume of course.
Got to love GM for interchangeability...

Yeah it did take up a lot of realestate. Does the push rod on the caddy booster have an eye on the end of it or is it threaded like the vette?

Re: Caddy Brake Booster Swap???

I just did this mod not too long ago. The booster was from a 1985 cadillac deville. The holes in the firewall bracket had to be hogged out a little bit but nothing major. The rod out of the back of the booster has to be cut to the length of the rod in the original jeep booster. You also have to remove the piston from the booster and put a dab of weld on the tip. About 1/8" will do it. As for the master cylinder, I just used the factory jeep part. All in all it was a very simple modification. Took maybe an hour.

Oh yeah, the rod has an eye and is not threaded like the vette. One of the reasons I went with the caddy rather than the vette. Wasn't too crazy about having a joint in the middle of that rod. The odds of it coming apart may be remote but if it ever did.....

I used a dual diaphram booster out of a '85 Chevy Caprice (when they ask if it has a vacuum switch - say no)and it fit the firewall and the CJ7 master cylinder perfectly, but the push rod had to be shortened about an inch. I had access to an Oxy-Acetalene torch, so that was no big deal either (pack around the rod with a wet cloth). If you do this, stop and get 6 new metric nuts as the CJ7 threads are SAE.

Good Luck,
