I heard somewhere that the disk brakes off the rear of a Lincoln can be put on a Mustang.Is this true,and if not, is there another set up that will work?Andy

The brakes from a Cobra would be the best to get. drum to drum for the whole rear end so to speak is the best, but I believe the Lincoln Mark VIII rear will bolt right in.

Since this in posted on the 70-93 Fox list I have to assume you have one of those year Mustangs. If that's the case the best rear disc brake setup for the money is the Turbo T-bird setup as its retains the 4-lug wheels. If you want to convert to 5-lug then the Lincoln or 93 Cobra setup would be the way to go or you can get the 94 and later rear disc brakes. the only problem with all of these 5-lug setups if the longer axels they all use and the wider track that results. Depending on your wheel and tire size you may or may not have clearence problems. IF you're planing on converting to 5-lug and do not yet have wheels then this should not be an issue as you can purchase the correct offset wheels.

GREAT CALL JIMB!!!!!!!!!!! I had forgotten about the turbo coupe's having disc brakes. That really is the best replacement if you can find 1.

Versallies brakes are too large and different bearing. Have the setup in my 74. You'll need the turbo's proportinong valve and or an aftermarket to complete swap. There was an article in 5.0 I think that listed a anti moan bracket to stop the unwanted chatter. I can't remember for the life of me who made/what issue etc. Maybe someone else might.

My Gransmother has had a 1982 Lincoln Continental since it was new. This car has 5-lug rear discs, and is a fox-body car. I've seen several in junkyards (built from 82-87). I don't see why these wouldn't work as well. Anyone tried it?

Next time someone goes to a junk yard, Measure 1 just for kicks. Then we will know for sure how good of a bolt in it will be.

Thanks for the idea, and welcome to our side of the forum Charlie.

The SVO Mustangs came with rear discs, did they not? I believe they came with rear discs, and larger front discs than a stock 5.0 and were still 4 lug. If anybody knows for sure if I am correct, or incorrect, go ahead and call me stupid...won't be the first time.

I do believe you are correct. I remember them also having a different Caliper on the front as well.

The SVO Mustang had a 5-lug bolt pattern. It used the Lincoln Mark VI or VII brakes front and rear with an offset different then standard V-8 Mustangs.

What's a fair price for used Turbo coupe rear disk brakes (calipers, rotors, brackets, and hardware)? I've found a set for $150. Would you have to change the master cylinder to use the rear disks on a '92 LX 5.0?

You should talk to your Ford Authorized, factory trained techs about this.

OK, now that I cannot be sued in case your car explodes...

The factory master cylinder works for a SN95 brake setup that gets transplanted into a Fox-chassis car. You NEED, it is really important, that you change the proportioning valve to one with rear disks. Disk and drum brakes require different pressures to engage, and if you leave the proportioning valve the way it is your rear disks will lock with the slightest touch of the brake pedal. That is not a good thing...

Greg, If you are only buying the hardware and it is all non guarenteed stuff, I think that might be a bit high. I would think you can buy a whole rear end for that in a yard. I dont get to dig in yards much, but last time I checked on a rear end complete, it was 100 drum to drum.

You might look into a 93 cobra master cylinder and proportioning valve set up as it had factory disc brakes.

Thanks, I've decided not to buy the stuff.

What type of rear did the Turbo Coupe have, and is the width correct for a Fox Stang? What years do I look for? What about the Mark VIII rear, what years?

Ok, here's what I know about swapping a T-bird axle into your 79-93 Mustang.

You would want to get a differential from an 87 or 88 T-bird Turbo Coupe. These difs are the 8.8 unit (86 and older used the 7.5), and come with either 3.55 or 3.73 gears, depending on if it come out of a manual or auto trans car. These difs do have traction-lock, BTW. The disc brake set up adds 0.75" of width on each side over the drum 8.8 (total of 1.5").

In order to complete the swap you will need a master cylinder from an 86 SVO Mustang (2 port style), which has a larger piston (1.125"). This should bolt right in, for most applications. If you are putting the car in a pre-85 model you may have to come up with a custom brake line to attach to the lines on the dif, due to a slightly different design used on the pre-dual exhaust cars. Use the e-brake cables from the 84-86 SVO, as the stock units are not compatible with the T-bird brakes (unless your car is a 93, for which you need to use the e-brake cables from a 93 Cobra). One other thing that you will also have to do is redrill the mounting point for the quad shock 2" lower on the T-bird axle to have it line up for the Mustang.

If you want even more info on how to do this swap, and perform other upgrades to your Mustang's brakes take a look at http://www.proaxis.com/~bobbitt/mustang/tech_page.html#rear This page has lots of tech tips to make your car stop better.

Hope that this helps a bit!

Cheers,
Ian http://79indypace.stangnet.com

FYI, I am in the process of collecting the parts to do this swap into my 79 Mustang Indy Pace Car.
