rearend is ready

[eddmann55]

i got a rear with rear discs, and 3.73's off donstang from an 88 s/c, I cleaned it up new calipers,rotors, brake lines, now it's ready to put in my 88 vert

You know the TC rear is 3/4" a side wider right? Also, the quad shock brackets are at a different location (but can be redrilled). Also, did you copy the TC brake line routing, or copy you fox?

i know about it being wider and i need to drill holes 2" lower for the quads, but i copied the s/c lines, should i have copied the fox?

Take a look under your car, but on mine, the brake lines (84 fox) come down to where the breather tube is on the right axle tube. On the TC, they come down on the other side, so your rubber line and block might not work.

ok, thanks a lot, don said if i had problems you were the guy to talk to about this, i appreciate your help, i never even thought about that, now i know to look for that. while on the subject what master cylinder do you recomend, one from t/c or cobra, or will any ford near that year with rear discs work

[Martin0660]

Well, the disc brake TC master cylinder is a electro-mechanical (TEV's) system, so no help. I know folks that have used the SVO master cyclinder, as well as the 93 cobra master cyclinder too. My buddy Frank has the SVO master cylinder on his right now with the TC rear and says the brakes are okay, but he has small fronts. I actually think the cobra and SVO might be the same, but never looked into it. My car is all SVO brakes, so of course I use that master cylinder and it works great.

I think any of the disk brake master cylinders will work, the bigger problem might be with the proportioning valve. This might help you.....

i already bought an adjustable prop valve hope that works

BTW, the SVO is the 1 1/8 bore cylinder so you can later get the Lincoln / SVO caliper (73mm bore) and have a decent system on the semi-cheap.

I have a related question. I'm using the larger SVO calipers on the front of my 85 GT do you think I should use a different master cylinder?

From what i've heard from folks going to the 73 mm caliper bore (Lincoln / SVO) Yes. You might try it, with your stocker, but I think you are going to get better pedal feel with the bigger SVO style bore, surely you will need to move more fluid with the larger piston, so if you dont change MC bore, you will need to stroke the pedal further for the same clamp force. On the other hand the TC guys with the TEV's system do get away without a change (common upgrade for them).

You can pick up re-man master cyclinders at chain type auto stores for releatively cheap, although from what I've seen, they arent aluminum like the real SVO unit so I expect they are using another core..

BTW for anyone doing this type of swap. The Lincoln Mark VII and SVO calipers interchange (same casting), but generally if specified for a SVO they are going to have phenolic pistons. Typically the lincoln spec has metal ones. If your car sits for times, the phenolic can be troublesome. The next time mine hang i'm swapping to metal pistons.
