Reply to "Vintage racing brakes"

I am working on this now. I can't answer that precisely yet.
The Tbird caliper actually measures EXACTLY the same to the center of the caliper as the stock Girling unit does.
It is a LONGER caliper then the Pantera unit. That enables it to use a larger brake pad.
That and the four MUCH LARGER pistons give it much better clamping force.

Just as I write this now, I found the bolts that I need. They are not local. I need to order them and I will have them in a few days.

I PROBABLY will be able to answer your question early next week?

I think that the Tbird caliper will clear the inside of the 8" DT wheel. I don't think it will fit on the 7" wheel.

Those 7" I don't have anymore. Those I sold. I am using the 8x15 and 10x15 DT wheels.



It is also possibile that IF the caliper does hit the wheel, that one can use a two piece rotor.

The hat could be deeper which would push the rotor further inboard. The caliper can be spaced inboard by shimming.



I am using a 3/8" thick adapter (9.525mm) for the caliper.
So far it has the caliper centered on the rotor.

I won't know precisely until every thing is trial fit.

I have done this before on my Shelby and the fitting can be so tight that even 1/16" can be life or death on whether or not everything will fit.



I actually LIKE doing things like this. For one thing they are not supposed to be possible to do. I like defying the "experts".

They are like Donald Trump and will never admit that they are wrong even when you just proved them wrong, not by just a little bit but by as we say, "a country mile".

When I get this mounted up I'll take some pictures and post them.



The pads that are needed for this setup are the Porterfield R4S. That is a street pad but it is a just a little hard for the street and you need to get them warmed up, unlike the standard pad which is good even when cold.

The difference would be the high temperature limit is higher with the Porterfield. Much higher with the race compound but you will get killed on the street with that one.

When they are cold, it feels like you have no brakes at all?
