Andy, why didn't you tell me about it when we were on the phone this week?

What size is that MC? 1" or 1.125"? I bet it's the 1.125" power MC.

If the bore is the wrong size for the calipers you will never get the car to stop.

Grab my brake math spreadsheet and run the numbers.

When I had the big MC and the slider calipers I could have both feet on the pedal, my butt out of the seat, and still not be able to stop the car.

It magically fell in line when I put the AMG brakes on the car. The MC was perfectly sized for those calipers.

I bet the proper sized MC would make the problem go away. Those calipers were likely paired with a 1.031" master cylinder.

If I have the MC sizes correct you are down 16% on your brake pressure.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
