07+ Brake upgrade on a 00-06 NBS, is it worth it?

Is that like a Boy Scout badge thing ....... each rig upgrade yields a +1 ??

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.
Wondering if anyone knows of a decent master to look into as well?

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.

My experience in NYC ... they either failed to notice, or, they noticed, but they didn't care.

Yup, imo--depends on the individual looking. Bought my set from a TYF member parting theirs out.

When I was at the Barrett Jackson auction, I spoke with a vendor.. Wilwood.. Front slotted & red calipers. $1,600. But is their quality worth it?

If the 13th immediately successive 100MpH-0 panic stop stops as quickly / shortly as the 1st, yes.

I get the hint....... I should up-grade my audio system instead....

Why not just go for the 21+ 4 pot upgrade? That seems to be the best bang for buck brake upgrade for the GMT800.

I already have the ProStop slotted disks & red calipers ( they refurbish stock calipers).
They work nice... But always thinking about better stuff...
I am keeping my 17" wheels....

Interesting thought, but I don't really need that much of an upgrade or to spend that kind of $$, and I'm keeping my 18" wheels.

I must be late to the party on that info, I didn't know they wouldn't fit 18s! (new AT4/Z71s have 18s I think?)

I don't know if they would fit my Silverado wheels, but I don't really need that kind of a brake upgrade.

My ProStop rotors / drilled-slotted calipers work great..... ( '05 stock configuration )

For about the same cost, try the exact same thing as above, except '10 stock config.
To be clear:
2010 caliper brackets, calipers, rotors, & pads. You will be pleasantly surprised!

That's the setup I have on my 03. I also have the steel braided brake lines.Stops great.

Steel braided lines also......when I had the ProStop kit installed....
