What kinda driving will he be doing. For just the strip you could go light on brakes.

Like Craig said the brake petal will be hard to push.
Do it right and find something that will stop that baby on a dime.

it will be some street driveing but mostly strip

At a minimum

SVO M/C
SVO front calipers (73mm piston size instead of 65mm which are the size of GT)
Stainless steel caliper sleeves in the calipers (replaces the rubber bushing).
Adjustable brake bias valve

The only thing of question is if the SVO M/C bore will fit your manual brake adaptor hole, and how hard the pedal push will be.

thanks for the help.

When I did mine conversion to the T/C disc I had to gut the proportional valve with the kit supplied by Motorsport. The kit consisted of a single bolt that had the rubber tip removed and was a solid bolt. This gave equal pressure to the front and rear.

I also upgraded the M/C. The original has a piston diameter of 7/8 or something likt that. The old 84-86 SVO steal unit had a diameter of 1 inch. The 93 cobra also has a three inch but it is a plastic unit. The 93 Cobra one also only has three ports on it rather that the two ports.

Some say you will need an adjustable proportional valve that will replace the coupler on the passenger side firewall. I found that I did not need it. There is a bunch more stuff that has to be done on the rear to get the T/C brakes to fit. If you need i have a write up on how I did it if you want it.

Since all of that I went with the SN95 setup for the 5 lug conversion. One last thing. I have read somewhere that you could use the newer style brake booster that is on the 96+ to conserve space. Not to sure on what modifications it would take.

we have the t/c rear under the car now.the disc are hooked up.We just do not have good stopping power.

I would atribute that to the brake boost but since you are limited on the space I would look into the new style brake booster and see if you have room for that.

Ok, the SVO MC has a 1 1/8" bore. It will fit into MOST manual brake adapters. I have one on my 79 (460) with the Holcomb manual brake adapter. You will need an adjustable prop. valve to get it right. they are cheap and easy to install.

You will notice that with the SVO MC and Fox V-8 front brakes (be it Mustang or the 73mm Mark VII/SVO calipers) that you now have a very high pedal effort. This can be fixed!! You have to remove the pedal box from the car and move the pin anchor for the MC rod up about an inch. That will give you the leverage you need to hit the brakes and not feel like it's not stopping. You done have to shorten the pedal rod when you do this, but it will move the pedal down to a more comfortable position.

You will probably have to put a limiter on the pedal itself so that it doesn't pull up and out of the MC bore. Mine would come out under acceleration and if I went to hit the brakes real quick (end of the track) the pedal would have swung up over my foot and I would get it caught on there.

I eventually went to Stange brakes on the front. Man..... I'll never look back!!

Yikes! That sounds like it would be a little scary.
