Anyone add a Master Cylinder upgrade to their GMT800's? I have the NNBS setup, but need to do the master this week. Wondering if anyone knows of a decent master to look into as well?

I have the GMT900 front brake setup, but need to do the master this week.

I'd bet it's possible to upgrade my GMT800 Master Cylinder with a younger GMT900.
Have not found it necessary. Not saying I'm opposed to it, just that it's not needed.

My GMT800 MC, pumping on a 2010 Suburban front brake kit, has easily improved my 85MpH-0 by at least 20ft.
I STILL find myself underestimating how well my brakes will brake.

In order to further improve my braking, my guess is a fine-tuning of front/rear brake bias would be needed.

I'll admit to not reading all 500+ posts on this thread, but am planning this brake upgrade on my '04 Hoe for sometime during the summer.

What experiences have y'all had with the cores -- do the local parts stores check to see if you're returning the same style (NNBS) calipers, or don't they care if you're returning NBS calipers?

In other words, will I need to source some used NNBS calipers for the cores? NNBS trucks in the Upulls here are scarce, but I have some time to look.

If it matters, I may stick with local retailers, just for ease of warranty purposes. Any recommendations on certain stores and/or brands of (reman) calipers? The local stores don't seem to sell new ones.
