Rear disc from 85 Eldorado to 85 cutlass???

[Veltboy618]

I been wanting to do a rear disc swap on my cutlass & I found a 1985 Cadillac Eldorado with rear disc brakes at a local salvage yard so i can probably get everything I need for cheap. Both rotors which are the same bolt pattern& calipers are there & the proportioning valve but I dont know if I need that or not. I have read about people using these parts to do a rear disc swap but never seen pics after it was finished or heard any feedback after the conversion was complete. Is this a pretty good kit to put on my 7.5" rear end & what brackets will need to mount everything? I''m waiting to see Sickolds setup to get a better idea of how everything goes.

I wish you took a pic behind the rotor. It all depends on whether the Eldorado uses a 3 bolt axle flange or a 4 bolt flange. If it is a 3 bolt flange, it should work. But I'm sure someone else will chime in.

The main problem with trying to convert a 7.5 rear end to disc is its unique 3 bolt axle flange while most rear ends used a 4 bolt flange.

That's the rear rotor? I didn't know the cadi's were front wheel drive.

Cadillac built it's first ft wheel drive car in the late 60's It was an Eldorado also.

What kit does it look like they used here?

What gets me with those pics is that there's all this high dollar stuff and then you see a cheesy worm clamp on the axle. It looks like the e-brake cables are zip tied too. I could be mistaken, but those might be Vette calipers.

Looks like F-Body stuff to me :|
