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.
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....?

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.

After reading through all the pages I didn't see anyone mention the wheels I have as a trial till Deadbaffy asked and figured this would be a good first post. lol! I have the Texas edition wheels 22x9 with 31 offset and I can confirm they do fit with no mods AT ALL!!!! no shaving, grinding or spacers.
This is the initial mounting and crossing fingers they would fit!!! And yes, those are the NNBS front brakes as I had already done that mod some time ago. That alone was a good improvement over the stock brakes and I am hoping this will be even better. When I did that brake swap it was during shut down and I couldn't find stainless brake lines in stock anywhere and kinda forgot about them. They are new rubber lines at least but they are ordered and on their way and will mount them and bleed the brakes so I get an idea of how the NNBS is with stainless lines first.

I found a guy selling one caliper so I ordered it. and went to Autozone and "borrowed" a rotor for mock up. lol!

Mounted.

Pic showing the spacing, 2 washers I had on hand are just a tiny bit too much. probably just order the wilwood shims...

The "bar" across the front clears with about a little over a quarter inch of space at the closest part.

Clears the hub of the wheel. looks closer than it really is. It's at least a 1/4 inch. changing out that washer will move it back just a smidge more. Also you can see how the "bar" clears the spokes again.

I have a line on the rest of the parts to complete everything but waiting on the guy to get back to me today. Hopefully I will be able to get the rest of the parts soon and advise on the braking. My Tahoe also has hydroboost so I will be able to speak on that aspect of the swap as well.

Hope this helps someone and add my wheels to the list of ones that fit!!!
I still have everything just sitting there mocked up till I get the rest of the parts so if you need measurements or anything, let me know!

Was it confirmed that these oem 18” wheels will not fit the brakes?

Did anyone try the method 706 wheels in 18x9 +18mm (I have a set of these wheels as well. But they have 35’s on them)

For me, the washers are not appropriate, because you can clearly see, that they do not use the full contact surface that the brake caliper would normally have on the holder.

This means that when force is applied, the screws could bend back and forth.

This could cause vibration or worse, bending screws which could eventually break after a while.

I would definitely use washers that use the full contact surface of the brake caliper and the holder, to prevent this tendency.

Agreed, and that is why I said I was just using what I had on hand for mock up. All I cared about at this point is, will my wheels fit? they do so now it's on to get the rest of the parts and then install. The wilwood shims would work but I will probably have my buddy just machine a spacer to the right thickness and size. :)

Well, my install got delayed a couple days...when I was mocking up the brakes the other day, I noticed a little bit of noise starting in the hub bearing so ordered new ones. Unfortunately, Rock Auto sent me what was obviously a return that was defective as the box had about 10 lbs of packing tape TRYING to hold the box together and failing miserably. The bearing barely turns and when it does, it's not smooth and catches randomly on something. returned today and now waiting for the other bearing. Hoping by Sat. But that gives me time to smooth out the caliper a bit as the casting and flash on these are horrific!!! lol

For anyone who has done this brake swap, Did you use the later model dust shields? I noticed they changed from our 3 bolt hubs to 4 so didn't know if anyone tried or if they even fit besides the bolt pattern. Just curious.

Anyone who has done this live in the Bay Area of California?

I’m curious to see if my wheels will fit.

I finally got my replacement hub from rockauto so those parts are on and I used the waiting time to clean up the calipers a bit....My original deal fell through (read, sold them to someone else...hate craigslist sometimes) But found a guy who upgraded to the wilwoods last month and still had his originals in boxes.

Didn't go all crazy on them, just a little smoothing and cast flash removal....
