Another Fox rear disc conversion topic
I just picked up 2 axels, calipers, discs and brackets from a fellow TR bud. He says they are out of a 93 cobra. They are 4 lug. What else will I need to do to have these work proberly? Do I need to change master cylinder or valve below it? Thanks for the input. I will post pics of the stuff shortly. I am putting tem into a 90 notch with an 8.8 rear.

Any time you swap the rear to disks you'll need a new master cylinder designed to move more fluid to the rears, and you'll also need to mod the prop valve below it for the same reason.

Bro,
I did have a mutha, but it was my own doing. I used a Lincoln rear and that was most of it. The axles were too long and I did not like the tire rubbing. I went back to a stock lenght axle and then had to modify the caliper mounting brackets. I used the brake lines from the Lincoln rear and did not change the master cylinder yet. I am going to do that, as the brakes are a little soft.
However, with your setup, I can't see you needing that. The 93 Cobra did not come with a different master cylinder that I am aware of. I doubt the brake lines will be an exact match, but I am sure you can work something out there? I would look at replace those rotors, as they are cheap these days. I picked up new ones for the conversion for $22 each. It also looks like those axles have the anti-lock gear pressed on them? Those might need to come off, but it is all off an 8.8 with the same body width. I would think you are going to be much better off than the path that I took!

Just as a matter of semantics, those brakes are out of an 87 or 88 Thunderbird Turbo Coupe. It doesn't really matter since they are the same as the 93 Cobra, but as Brett pointed out, they have the ABS exciter rings, and 93 Cobra's didn't have ABS.
