Unless I've missed something here, yes, you will have to adapt and/or change the brake lines to hook this up. Hopefully, guys who have BTDT will chime back in.

Just a note; Classic Tube ( 1-800-882-3711 ) will make up any configuration of lines you want. Steel, Stainless Steel, Polished or unpolished. They work better than new, with late model flares & fittings or early model flares & fittings, Or both mixed for the custom jobs. Have a great one. Gene

I had an '81 Camaro with stock aluminum master cylinder with a plastic top. '81 was the first year they used these in the F body cars. Would one of those work in our cars?

Looking at the pics posted by 70LS1, he is running manual brakes. I am curious if there is any hood clearance issues with running the C5 MC with a hydro boost. It would push the MC forward and just wondering if it would clear the hood?

Another consideration for this mod, might be the heat transferred to the MC. I notice at the drag strip, that the stock MC gets quite hot, which can contribute to the fluid boiling. I was going to install
a modified starter heat shield, but this would be way nicer, and save weight. The Wilwood piece, while expensive, seems the most appealing...

It has to be some kind of joke.

The aluminum master for a 2000 C2500 Chevy 3/4 ton Pickup has the proper 1.125" bore as the C3 power master and has the same threads, so no need to fuss with adapters or modding the lines. Has the short piston for the later short rod.

This thread is almost three years old. Even though it is old, I bought a c5 master cylinder in 2007 along with c5 calipers. Parts are still in their boxes!!!!! I have a lot of parts I have not put on my vette.

OK,
Let me clarify this:
I already have the metric unions and lines, just need to know if I need to reverse the lines as on some other Master cylinders or can I connect it as per original?
This is from other thread:
same line fitting size, BUT they are backwards. The front and rear lines are flopped VS the C3. (NOT refering to C5 MC)
The stock C3 MC has the larger fitting in the rear where that newer one has the larger port up front
Edit:I think I have worked it out:
C3 front line is smaller in diameter comparing to the second line. I will check my unions and hook it up as per the C5 union diameters

About the C5 brake calipers, I have tried searching and have not came up with anything in the C3 section. Anyone have a link or know what it takes to use them?

I used a C5 master and had custom lines made locally since I can't make metric bubble flares to save my life.
I got my fittings from either "inline tube" or "classic tube" can't remember which one.
The front brakes attach to the rear port and the rear to the front. This is backwards from the C3, but the lines have to be tweeked to fit anyway. The front brake line uses a 12x1.5mm ISO bubble flare on a 1/4" line. The rear uses a 12x1mm bubble flare on a 1/4" line. The only fittings I could find were for 1/4" line so I have 1/4" for both front and rear then an adapter to drop it down to the 3/16" on one of them to match up to the stock lines.
And both feed to the stock distribution block.

If you need the metric unions, let me know as I can get them brand new from a local brake parts store
Does it matter which line goes where (MC/ line distr. block) providing the lines fit the unions with no leaks?

I picked up a C5 master a couple of weeks ago. I have pulled the reservoir off and cleaned it up. I also got the lines from the C5 and thought about using those fittings if possible. I have not really looked at the existing C3 brake lines or the new C5 lines to see how everything lines up. We will see if it is possible.
About the C5 brake calipers, I have tried searching and have not came up with anything in the C3 section. Anyone have a link or know what it takes to use them?

My brother is upgrading his C5 to bigger, better aftermarket brakes, and he says I can have his C5 brake leftovers. I think I am going to stay with the C3 brakes, (the C5 brake upgrade does look like a lot of work) maybe with an upgrade to the aluminum Wilwood stock replacement calipers. Although, I am a little worried that the stock size C3 rotors will look a little wimpy if I upgrade to 18" wheels, so I am a little conflicted about the whole thing.
