Brembo brake setup

If you are going with manual(non-power) brakes you don't want a large piston master cylinder.

Wilwood offers several proportioning valves with different inlet/outlet sizes and styles.

 

That is usually the case. My smaller Wilwood setup on my '70 used 7/8" bore and my larger Wilwood setup is 15/16".
They figured the right piston size by using the caliper piston areas. Above my head stuff.

I wish I could help you with fitting sizes. I had to use adapters on the lines in and out of the Wilwood proportioning valve with the stock master. They were available at Auto Zone. There are not a lot of options out there for different sizes. Just some English and metric.
For the new setup, I gave up and decided to do all new lines. The stock stuff does not clear subframe connectors, sits too close to the headers in the engine bay, etc....

 

With a bore that big you will using a lot of pedal pressure for little braking.

You need to thing of the bore size as pounds per square inch. Smaller piston higher psi for same effort as opposed to lower psi for larger piston.

You move less fluid but at a higher pressure.

I have been down this route before. I went with the large piston. I could stand on the pedal and not lock up the brakes. Very scary in a panic situation.

 

Also, make sure you use the hole on the pedal that gets you the highest pedal ratio.

The one that was on my car came from a late 60's to early 70' Corvette. It was a 7/8" bore.
I want to say '68 but my memory is not that good.

 

Try the Mopar style. Alu body, weights next to nothing. Just need to elong the holes with a grinder a bit.

 

Early C3 Corvettes had manual disc brakes and should bolt up on second gens fine.

What size wheels are you planning to run with the 5th gen brembos?

I'm thinking of doing a similar setup but not sure if my wheels will fit.

 

OP, I was looking into using Camaro brakes as well, just be mindful that 5th gen Camaro wheel bolt circle is 5x120, Corvette is 5x120.65 or 5x4.75" the only real answer is that no matter how you slice and dice it 5x120.65 ain't the same as 5x120 having said that .65mm is just a shade over 25 thousandth of an inch which is shared by 5 studs, why did GM do this?? some say it's same, I say well how can it be!! Dose it work, apparently so but I've never tried it, anyway I think this topic has been beaten up all ready, there is a good thread in here somewhere.
