Title: Budd conversion
Post by: John B. on August 13, 2008, 12:53:30 PM
Hi Fellas; Has anybody tried using the later dual reservoir M. cyl & dual diaphram booster with a existing  Budd caliper & rotor set-up? The Budd parts are all but obselete now!
 I would appreciate the input, John

I had a Budd car, I understand.
 
Firstly, what are you working on?  If it's a pre '65 Imperial as yer handle suggests what I'm going to say may be useless.
 
A '73-up disc setup is the way to go without sinking a ton of money into your car.  Look at this thread:
 
http://moparfins.com/forum/forum_posts.asp?TID=1478 (http://moparfins.com/forum/forum_posts.asp?TID=1478)
 
and this thread:

Snotty's pictures are nice and simple and self explanitory.  If you can find the right donor car your worries are over.  Booster, master, prop valve, spindles, caliper brackets, and dust shields are what you need.  Aftermarket calipers (master cylinder perhaps) and rotors aren't too badly priced new and will make the swap reasonable and nearly trouble free.
 
The big cheez will chime in for sure.  He's done a few conversions and has the hands-on experience.

Hey, I'm a celebrity!  (http://www.moparfins.com/forum/smileys/smiley4.gif)
 
John, do be sure to get the correct stuff, whatever you do!
 
But as for your question, I do not know.  I installed a correct disk brake Master Cylinder, but I already had a dual-res system.  It was easy to make the swap.  There are people on this site that have done single to dual swaps.  I hope they can answer you.

A '73 donor car is all you need.  I found a '73 Fury locally a while back but it's not fer sale.  I haven't been to a bone yard for a while, but those donor cars were out there.  Ebay is another option, I know a few members bought their disc set ups there for a decent price.
 
Polaraco and Thrashingcows have done this conversion with great success and are here to help just like Snotty.
 
My '68 NYer had terrific brakes until a caliper blew out.  Upon inspecting that I found the lower ball joints to be rather sloppy too.  It wasn't long after this when I realized I had a parts car, all of the needed parts to fix it were made from unobtainium.

Matt, I've also had '73 discs put on Chaz, and the stopping is MUCH improved!
The best thing about the '73 set-up is the price of the rotors (rockauto.com lists the RAYBESTOS Part # 7018R at $67.79), which are single piece, while the '69-'72 stuff are next best, but you get two piece rotors.  And rotors cost almost $160 according to rockauto.com (ACDELCO Part # 18A1352), but they ARE available.

Ooops...  sorry Moe (http://moparfins.com/forum/smileys/smiley9.gif)  I forgot you upgraded Chaz's binders!  You've blinded me with too much shiny paint and handsome interior (http://moparfins.com/forum/smileys/smiley36.gif)

Hey guys; Thanks for the input! I'm currently on the trail of a set of 73 spindles & rotors. The wagon currently has the single pot master, but we will switch that puppy to the dual master & booster. John (http://moparfins.com/forum/smileys/smiley2.gif)

I was able to get a pair of '73 rotors for $91.00.  Unfortunatly, they were the worng ones for my '71 set-up.  It cost me $415.00 for the two '71 rotors.  Ugh!!!  (http://www.moparfins.com/forum/smileys/smiley11.gif)

I did a drum-to-disc-swap on my '65 300 convertible to '73 spindles and dual MC.
The easiest swap I've ever done. I could even re-use the original brake-hoses.
Later on I bought 2 replacement rotors from NAPA and they were $34 each at the time.

I noticed the spacers in your photo.  Do you still need to use those?  I was able to toss mine with my disk swap.  The bonus is I no longer have the high-speed brake vibrations I had before the swap for whch I'm grateful.  I attribute that former shaking to the need to use spacers.

Who says I ever used the spacers...(http://www.moparfins.com/forum/smileys/smiley2.gif)
I guess the pic is a bit misleading because of them, but they had nothing to do with the discbrake-conversion.

Reason the spacers are in the pic is that I thought I would need them when I would mount my 14" spoke wheels, but I didn't.

ok fellas; I'm confused!! (http://moparfins.com/forum/smileys/smiley5.gif) Whats the difference between the 73 spindles & rotors and the 74 & later?  John
Title: Budd conversion
Post by: Snotty on August 19, 2008, 04:14:20 PM
Nothing.  Try to find '73 and newer, avoid the older set-ups.

Post by: Ken on August 19, 2008, 06:32:34 PM
I believe the '73 spindles are a one year only deal, as they kept the lower ball joint of the '65-'72 drum cars.  I believe the steering geometry and lower ball joint was changed on '74-'78.

You want confusion? Take a good look at the rotor in my photo above...
Try and find the brand of that rotor... (http://www.moparfins.com/forum/smileys/smiley36.gif)
