You won't regret it on an '02, for a certainty. Huge difference is stopping power. My '03 tows 4500lbs everyday and this upgrade has saved me two or three time since I installed it last year. Stopping 11,000lbs with the factory brakes was always sketchy. I have the Atomic Fab Viking coilovers. You won't regret that either. Has a similar ride to my '15 HD 2500, except less jitters from the rear since I have the 3" drop coils with Bilsteins back there. Why so many tranny's? You have a supercharger?

Well damn. I just read that and my happy feelings left. I just got 2015 LTZ wheels and had them powder coated. Did you have the 5 or 6 spoke? And where wouldn’t it clear?
Answered my own questions by going back and reading their the entire thread. Bummer. NNBS upgrade it is then. For now.

There are a few people in this thread that said the NBS 2 piston rear will go right on an NNBS with just rotors, pads, and calipers. My concern was the parking brake but based on a quick look on Rock Auto, it looks like the parking brake shoes are the same just the retainers are different (which gives them different part numbers if the retainers are included with the shoes).

2 piston upgrade the parts are listed in the description

Anyone have a link or part # to longer braided steel front hoses?? I can't find info on here and been looking for the last few days. I saw someone posted something about the stock hoses are a bit stretched and would prefer to buy longer hoses for more slack

These are the ones I used.

You could always go Suburban, since the hoses aren't prebent. That should give you enough length. Might check the regular cab trucks, too. The wheelbase on the Extended and Crew cab trucks are longer than a Suburban, so they are highly unlikely to be good for your Escalade.

I finally towed another vehicle with the Caddy with these brakes on it. They worked incredibly well and I could definitely tell an improvement over the originals.

Yep. Having this setup while towing with my '03 Yukon XL has saved me twice since I installed them.

I just read this entire thread, a lot of good info. Reminds my why I love this forum.

Seems like it could be the ultimate brake upgrade.

However, possible plot twist…

The 2021 Tahoe 9C1 PPV and Silverado PPV (and maybe the 21 Esky?) come with 6 piston Brembo calipers and massive 16” rotors.

Wouldn’t this PPV setup also fit?

Also, it appears that the non-Hydroboost 1500 NBS, NNBS through 2018 all seem to use a 1 1/8” bore size MC (aka 1.125”), while the T1 uses a 1 5/16” bore size MC (aka 1.3125”).

Would be interesting to find out whether the 9C1 PPV master cylinder are the same size too (assuming they probably are).

Would be curious to know if they are bolt up also.But i can bet the price is 2-5000 vs 2-300

It appears this BBK package (RPO PPV J55) might also be available on the LT and LS trims as an option (part# 84766666), so would likely just bolt up (albeit with some washers like the 4 piston T1).

However, indeed the bang for buck price-wise does not compare at $2100, but perhaps it will drop in price with time, or come up on eBay and/or junkyards.

I just recently checked junkyards for ***** n giggles and there is a LOT of 2020+ donor vehicles out there. I’ve had my Yukon done for about a year now and I love it! Definitely the best bang for the $. IMO.

Have you (or anyone else here) experienced the same thing as in the video regarding more pedal travel and more pressure needed to really lock up the brakes and/or activate ABS in an panic stop?

So, if TheKingCoopa didn’t accidentally leave some air in the system (in the video), and .1875” difference in bore size really makes that much of a difference after adding 2 pistons up front and 1 piston in rear of each caliper, maybe upsizing on the MC would help for the folks who don’t want to go the Hydroboost route after all?

I've had mine done for about a year and never experince any pedal travel or pressre issues. I tow a 4000lb trailer daily and brake fade is a thing of the past. My truck being a NBS already had 2 piston rear calipers. I don'tthink there an issue with the MC volume being to low on these models.

Does anyone know the part number for the Goodridge stainless steel brake lines that will fit this mod?

Would it just be the ones that fit the 2019+ Silverado? Or the ones for our NBS trucks?
