While at the wreckers yesterday I found what looks to be a '78 Imperial Lebaron, It's sitting right on the ground with no wheels on it, and it has rear disc brakes on it. Now this is a first for me, I wasn't aware that these beauty's came with them. Are these rare? I only had a tape measure and a set of keys with me otherwise I would ripped it out and brought it home with me.

 

Not sure if it is rare but if you have a vehicle with drm brakes where that axle will fit, I'd grab it.

 

Make sure to get all of the parking brake setup too.. Personally I would rather have drums in the rear

 

Does this help? http://www.moparaction.com/tech/archive/disc-main.html

 

That set up is Imperial only and just a few years. Not sure what all it fit's. check at the c-bodydrydock, for more info. I seem to remember that parts are hard to find if available. So you could probably retrofit it to some thing but maintaining it would be expensive at best. No market for them or thier parts.

As posted in the article linked above;
Much has been written about rear discs. Everybody lusts after the early-‘70s Imperial units. In a word, don’t! Chrysler engineers have told me, point blank, that the only reason they went to 4- wheel discs on any car (possibly excluding the Viper) was “competitive pressure”. They feel there’s little performance gain. Then there’s the fact that the Imp parts are now scare as hen’s teeth, and require custom-length axles to install on 8.75" axles (unless you want to give up your beefy Timken rear wheel bearings for rinky-dink ball-type bearings.)

 

Thanx guys for the info, all the vehicles I own are rare in their own way. My daily driver is '51 International 1/2 ton 4X4 short box truck, My wives daily driver is a 1995 Chevy Tahoe with 6.5L diesel 1 of 1200 made that yr. Yamaha XV 1000 only made for a couple of years, and of course my '76 NY'er. I get weird looks from people after I tell I'm fixing it up and it has the 440.

So I think I'm going to grab everything I can off that car, and put it in the attic of my garage for now. I don't think that I would drive it enough to even wear out a set of pads if I put it in, this car is retired a long haul trip now and then with a car show or two and couple of milk runs thrown in would be about it.

 

also, keep in mind that if the gear ratios are different it's going to throw your speedo off a little, and change a few other things, as well. nice find!

 

try finding pads rotors etc, u wont
