Will be doing the '19-'21 Big brake upgrade on my '00 Tahoe.

Wondering if anyone who has done this big brake swap, also did the Hydroboost AND the bigger master cylinder upgrade?

As a comparison... The stock squishy brakes on the NBS 1500 came with a 1.125" master cylinder and vacuum brakes to push 8 brake pistons (4 front and 4 rear), while the NBS Escalade came with Hydroboost AND a bigger 1.33" master cylinder, even though it had the same amount of pistons (also 4 front and 4 rear).

Further, the 2019+ Silverado comes stock with Hydroboost and a 1.31" master cylinder to push 10 brake pistons (8 front and 2 rear).

So, if we are aiming to push 12 brake pistons (8 front and 4 rear) in our NBS 1500's, wouldn't it make sense to increase the master cylinder to the Escalade 1.33" master cylinder (should bolt right in) AND upgrade to Hydroboost to closer match what those ass bigger calipers have pushing them in the 2019+ Silverado?

Btw I believe the part number for the 1.33" master cylinder from the NBS Escalade is NM4074 (if RPO code JL4 not present), and NM4074A (if RPO code JL4 is present).

I'd have done all this already if I could get my hands on the calipers

Hey can anyone point me in the direction or know what hydro boost you can swap in? I currently have stock hydro and master in my Denali trying to upgrade the whole system at once.

Sorry, I know its an old thread, but has anyone tried this? or is there possibly a thread someone has tried it that I missed when searching?
