I replaced the BUDD Brakes on my '69 Imperial with a complete Kelsey Hayes single piston floating caliper setup from my '72 Imperial parts car.
It's basically plug and play as you can just swap all the parts over from the donor car.
To be exact, I replaced the following parts which are all different from the BUDD parts:
- Spindles
- Caliper Brackets
- Calipers
- Hubs
- Discs
- Dust Shields
- Brake Lines
- Brake Pads
- Proportioning Valve / Metering Valve (Combination Valve in 72)
I changed that as well because a friend who did the conversion before told me with the original '69 Proportioning Valve, the K/H Calipers would drag.
Later I decided to rather go with a brand new wilwood proportioning Valve instead since I can adjust the preasure on that.
Beside these original parts, I replaced all the wear parts which are readily available EXCEPT the Rotors with the 5x5 Imperial Bolt Pattern.
These are not available at all, but the 5x4.5 Chrysler Discs are the same, available and a mashine shop can drill the 5x5 bolt pattern into them.
You can check my
Dropbox for pictures of all the '72 donor Parts if you want:
And/or you can check my
build thread for the overhauled parts.
I hope these information are what you are looking for.
