Will the Gmt900 booster and master cylinder work on gmt400?

[1998_K1500_Sub]

I'm finding out that I'm not liking the nbs master cylinder swap. It's a firm pedal on bad brakes. Oh well, it was worth a try. Putting new rotors pads and wheel bearings on it next week. I can really tell the rotors are warped now.

If you don’t already have the larger-bore, non- “low-drag” JB7/JD7 calipers, consider installing them. They avoid the issue @Schurkey mentioned above.

Thanks for the links and advice. I'm looking into the jb7 upgrade now.
