Help me stop!

Well, my car's pretty light. 3209 with me in it. I THINK my master has a 1 inch bore. It's a Raybestos #mc36406. It's the second one, so far. I do have a Russell prop valve to the rear. Also I think EBC's Yellow Stuff pads are NOT ceramic.

I have to get this sorted out. I just spent a buttload o' money on engine and it's gonna be a beast. It HAS to stop better.

I hear about a valve in the block that needs to be centered or something, but can't find any hard info. Thought about just ditching it and using a "T".

Do you guys think a smaller MC bore would help?

I'm completely puzzled. I'm certainly no brake rookie. That's why this is killing me.

Please keep the advice coming:coffee2:
