Stealth,
I can't find the "drums to disk" thread you mentioned. Could you provide a link please?

 

And when its all done, it will still stop the same. Yes you will have bragging rights to having 4 wheel disc but not that much will change in actual use. I think you are in for alot of either fabrication and/or money with no real benefit.

How difficult would it be to remove the rear assemblies? Also, what year(s) of Fleetwood would fit my car?

I found these links about the benefits of Disk Brakes vs. Drum Brakes:

The following is something I stumbled across during my search on the differences between the two. It was posted on another forum:

Following are typical pros & cons for both disc and drum brakes:
Drums

• Pro - Less expensive since they're already stock on Broncos
• Pro - Drums work better then discs as emergency brakes
• Con - They stop poorly when wet and can get clogged with mud
• Con - Stopping power can fade with repeated hard braking
• Con - Larger tires

Discs

• Pro - More consistant, straight line stopping power
• Pro - Dissipate heat better to stay cooler
• Pro - Less affected by water or mud
• Pro - Easier to maintain and faster to replace pads then shoes
• Con - More expensive to install (but maintenance costs should be less)

Are all these things false? I'm not trying to be rude or anything. Like I said before, I'm still new to all of this. I'm just trying to get all the facts I can.

 

78-80 Fleetwoods had rear disc but they were rear wheel drive. There is no guarantee they will work on front wheel drive car. The problem you have is GM did not go to 4 wheel disc in most models until after 2000.

 

The body type on your car is classified as a "C" body. Ck a Hollander interchange manual at a wrecking yard

 

Thank you all for your help. Any other helpful input would be greatly appreciated.

 

Sorry to bump an old thread but I'm also thinking about doing this on my 85 DeVille and this seems like a pretty useful thread to plug into.

The biggest problem right now is that I can't find any other C body models that had rear disc brakes (even the ~92 Fleetwood didn't have them, amazingly). Meanwhile the other Cadillacs from that era seem to be too different (Seville has
rear leafs?)

Anybody got any data on any of this?

BTW, wikipedia says the 1st and 2nd generation Buick Park Avenue used the C-body and it looks like the 2nd gen (1997-2005) used rear discs. That is about the closest I get to anything.

 

May I please have the year, make and model Cadillac that you acquired those bracket from PLEASE??
