vac brake conversion donor?

[Alaskabuick]

I have an 84 (i think) non turbo parts car. Can I use the vac brake on it for a conversion on my GN?

Thanks!

yes.. a Regal is a Regal..
actually, any G body can be a donor, but a 1990 Caprice has a bigger booster that is a bolt in deal.

I will add this tip for people thinking of going with BAER brakes. BAER recommends a 15/16" bore size for their brakes and the 1986-87 Monte Carlo SS vacuum brakes happen to have the 15/16" bore size making them a perfect upgrade for the use of BAER brakes...

 

[87-WE2]

So the ideal setup for baer (will get there one day) is '90 caprice booster, '86 or '87 mcss master cylinder? Just taking notes for a few projects down on the list.!!!

i'd think that a 15/16" bore master cylinder would be pretty weak feeling with a booster and PBR calipers- i ran a master cylinder with that bore size in a manual setup with the C4 Vette front brakes in my Nova, and it felt just perfect.

Only IF the Caprice master cylinder has a 15/16 bore size! I'm not positive what they have but I do know for sure that the MCSS does.

(87-WE2 ) I'm not too sure on the caprice booster mixed with the MCSS master. I got all the MCSS stuff and my brakes work fantastic! I have video's to prove just how well they work.

I was actually looking at the Caprice one as it has a bore larger than 1". Question I have is, is it possible to go TOO big? I'm running C5 front brakes with 13" rotors and SSBC Tri-Power calipers along with the SSBC rear 11" disc conversion.
