Do I have the right MC?
I have started my brake upgrade this past weekend and need to know if the MC I bought is correct for what I am planning. I have the stock brake booster (72 A body), but changed to a big block vette style MC with same front and rear ports. The MC is for a power brake set up with a 1 1/8 bore. The front line is 3/16 to the line lock and the same down to the T block I put in place of the original proportioning block. So the front is complete. The rear originaly has 1/4 tube from the MC to the prop block. With the new MC, it is 3/16. From the MC it is goes 3/16 tube to adjustable prop valve, then to the main line (that I disconnected from the original prop block) which is 1/4. I need to get an adapter for that yet. Does this set up sound correct?
thanx

MC bore size should be determined by the calipers you are running. Is this a stock setup or something aftermarket?
Your hard line sizing sounds fine for a disc/disc setup.

We've debated the hardline sizes before. I don't recall what we concluded. My stuff is all 3/16".

It was concluded that it really didn't make much of a difference for most swaps.

Do you still believe in all the things that you stood by before? Are you out there on the front lines, or at home keeping score?
Do you care to be the layer of the bricks that seal your fate? Would you rather be the architect of what we might create?
