4 Piston Big Brake Upgrade from 2019-20

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?

I used the NBS kit for my '03 Yukon 1500. Got it from BuyBtakes.com for $160. Part #14175. I will say that I was alittle disappointed in the quality from Goodridge. The splitter for the rear brakes was defective and I was unable to use. It had been several months since I purchased, so I was unable to get it replaced. I assume the 2019+ lines would be different for that body style. The only thing you're changing is the calipers which have the same fittings. Everything else on the truck is still NBS.

Ok - need to resurrect this thread - started some 2 years ago! How's everyone's brakes holding up? Spen hours reading all these postings - very interesting. I see the calipers are back in stock. Looking for I guess confirmation/guidance? From what I gather the following parts are needed:
Calipers: LH - 13545382 (changed from 13536579)
RH - 13545383 (changed from 13536580)
Pads?
Caliper Mount Bolt (4) 15016308
Brake Hose Copper Seals (4) 210122386
Rotors?
Running 2002 Tahoe with these rims on 275/60R20s - (picture) - Rotor size - 13.5"? larger? How big?
Fitment - Any issues with clearance? Do you think I will have to grind off that 'bump' on the calipers?
Looks like consensus is a 1/2 'hardened' 'AGB' 1/2 washer as a spacer?
THANK YOU ALL IN ADVANCE!

Any consensus for rear replacements/upgrades?

I tried this today on my 2015 XL with brakes for me 2023 Suburban and the calipers were so big the wheels wouldn't fit back on. So I need to figure out a spacer that I can run to make those work.

What wheels do you have?

You may need a different offset for this to work.

There is some DAMN good information in here, even for an NNBS guy! Thanks everyone!

Here's something to throw a wrench in the mix...

The 2021 Tahoe lists its 4p calipers as 84793057 & 58, whereas the 2019 6.2 Silverado 1500 lists theirs as 13545382 & 83. Anybody know the difference?

Maybe the 6.2's are bigger/beefier--since it's the 6.2....?

The 13545382 & 83 are the updated/superseded part numbers for the 13536579 & 80

Just wondering if the Tahoe calipers are different than the Silverado calipers somehow

Did you ever figure it out?

I have the 18x8.5 +24mm wheels from the Silverado on my Yukon.

I plan on doing this brake swap but would like to know if the brakes fit the wheels

Ok I’ve gone through 30 pages so I’m gonna just ask, sorry if it’s been asked. 04 Tahoe with hydraboost, and have the Texas style 20s. Will that clear or will I need spacers? It looks like there’s plenty of room but want to make sure.
