@@PeterHatch-mx7zc Yea

Now the rear

Thanks for the updates

Thanks, much appreciated!

Yes I 100% agree. I've tried to watch other ones the people don't know what they're talking about or they make the videos take too long. yours is the best most concise. The only thing is other people have used store-bought washers that seem to work fine. I wouldn't know where to get a machine shop to machine me out spacers. I'm sure it costs much much more than just getting some washers from the hardware store

Thanks for watching, it wasn’t too bad honestly.

@AutoEclinic I can get all the parts from the dealer for $800 out the door all ome parts

🙌🏻🙌🏻

Yes but those calipers are 2 piston, they are stronger than the 99-06 2 piston but the calipers in this video (2019+) are 4 piston which are way better and stronger

Thanks! It does make quite the improvement.

How did the upgrade went? I want to do it on my 03 escalade. Did you run with any issues on your yukon?

You’re welcome

​@AutoEclinic have all the parts before I mount them will the 18in chevy rims clear

Yes, that will work, taking you from a 12in to 13in rotor. But this setup will net you a hair bigger rotor with 4 piston calipers, which I don't believe we're available for the NNBS trucks. I think that's why he specifically says 2019. Although I looked on RockAuto for 4 piston calipers, and was unable to locate any. However, in the description, he provided the part numbers, so it becomes much easier.

@@jameswiz I put these on my 2003 Yukon years ago; CARDONE 18B4918HD 18-B4918HD (2007 2008 Yukon) and the matching 13in rotors.

@@jameswiz So weird the part number for the calipers doesnt match the ones I found at Summit racing. Their part number for one of them is ACDelco GM Genuine Parts Disc Brake Calipers 13545383

​@@joerivas9847The part numbers have changed multiple times over the past two years. As of 02/22/23, 13545382 and 13545383 are the current caliper part numbers.

Cool!

In real world use, it made a big difference. Especially when towing.

You won't see that. This is a sales pitch

@@raylaux8295 sales pitch how?

@@alfredoibarra9825 This is just advertising the conversion. Selling the idea. Not testing needed. Are you really that stupid?

Thanks!

The rear brakes on the newer trucks is still a single piston and I think even the same size as the gmt800. For a cheap big brake upgrade you can get the rear pads/rotors/calipers for a 05 Suburban. They're an inch larger and a floating dual piston.

Did you use the rear brakes from the newer trucks?

Not sure, have not tried it in that.

Thanks! To my knowledge it only works for the 07 classic. I haven’t seen anyone do it on the 07 new body style. I’ll look and see if they have the same knuckle and rotor.

@@AutoEclinic This should work on 07+ o because I did the 07-19 brake upgrade with the 2 piston caliper style and the 13" rotors. These 4 piston calipers require 13.5" rotors and the washers. The NNBS brakes work without any modifications and bolt right on on my 03-06 1500 Suburban

@@hatehereyes so for my 2007 Tahoe the calipers should bolt right up?

@@hatehereyes are you saying that I can but 2007-2019 brakes caliper and rotors on any 2000-2006 Silverado 1500? with no modification

@@TheBully010 yes, no modifications at all. Just get the caliper brackets, calipers, rotors and pads and everything will bolt right up.

No issues with any components used

You may need wheel spacers if you run a larger than 22” wheel. The caliper spacers are required no matter what size wheel you use.

Was there a lot of grinding involved or just minimal?

​@7resist7tyranny7 you grind where the hump is on the outer edge caliper

I haven’t

You probably already have your answer, but for anyone else looking for the answer in the future: No. The knuckles are entirely different due to a major change in suspension on the fourth gen trucks and fifth gen SUVs. GM moved the upper As towards the upper spring mount in the upper wheel well, instead of the older design that had the upper As on the chassis rails that has been mostly unchanged since at least the GMT800s. No idea how feasible a conversion would be, I doubt anyone has looked into it, later coil spring models might be simpler to convert, but older torsion spring models will probably be a bitch to convert; but at that point, is a conversion really worth it for the taller geometry at similar ride height. Surprisingly the brakes mount up the same despite the change, otherwise everything else is different including the wheel bearing mount, which might explain the wheel offset issue, why you typically need to shave the caliper's hump down or use wheel spacers on the older trucks with this conversion. The Brembo six piston calipers should otherwise mount up just like the current gen calipers do, though I'm not sure what wheel size and offset is compatible with them. And of course, the master cylinder upgrade given the holding power change. As for rears, they look the same, the same 1500 single-piston design, the same 2500/3500 dual-piston design, and the HD's have an entirely different design using four pistons but six mounting holes so who knows if these are compatible with a 2500 rear end (or even the front knuckles for that matter, I can't seem to find parts for the HDs as easily); if you want to upgrade from a single to at least a dual, pending HD brake compatibility, you'll either need to cut off and weld on new mounting tabs or do a full axle swap-- but given GM's lack of upgrades throughout the years, 1500s have always had single piston rears, 2500/3500s have always had dual-piston rears, and HD's are new for the current gen with their own update, and the SUVs sharing the 1500 package, I don't think rear brake upgrades are all that important.

Yes that’s what everyone does wheel spacers aren’t cool

No, we only had 1 set made for the truck in the video. You can go to your local machine shop.

Yes the kit for the front isc$2800 rear about $600.

No, sorry

Not sure

Had to get these made at a machine shop

Yes. The Tahoe, suburban, Yukon, Silverado, Sierra, all use the same suspension, brakes, etc.

Not sure, have not tried off a Colorado

Local machine shop, any machine shop can make them

Possible, not tried it on anything lower than 04

Probably not but we wanted to have a fresh start with all new hardware

New model

They bolted directly to the stock caliper. I just put new ones because of the age of the truck.

why would it not work, the caliper doesn't know where the pressure is coming from, just that it is there.

Thanks!

17 inch but make sure you check the offset

Not to my knowledge

The spacers were made at a machine shop locally. I have them the specs and they cut them out.

You can use a standard washer but we wanted a single shim per bolt

@@AutoEclinic Can you offer theses spacers for sale?

Had a machine shop make them.

GM dealership.

I have not seen anyone do it on the 2500’s as of yet.

Not sure

GM dealer and Rock Auto.

As of 02/22/23, 13545382 and 13545383 are the current caliper part numbers.

Went to a local machine shop and they made them based off of the measurements we give them.

2wd that I know of.

Stock hose for the 2004 truck. They worked with the new caliper.

18s and up, but some designs might need a wheel spacer so the rim don't scrape the caliper

Wondering the same thing. Obviously would need 8 lug rotors

Not sure on that one. Have not tried it on an HD

We do not, we just had a local machine shop make them.

Not that I have seen yet

Would they work on it tho?

Not sure, didn’t measure them before installation

It's the essential part of the equation when determining caliper clamping force. Did you know a 4 piston caliper has about the same clamping force of a "one sided" two piston caliper if all the pistons are the same diameter.@@AutoEclinic

Not that I know of

We had a local machine shop make them for us as a favor out of spare material they had leftover. I’m sure a local machine shop could turn those out pretty easily.

what size hole for the bolt & 15mm correct?

@@PONSAUTOMOTIVE any update??

The best brakes for a 1500 GMT800 are the suburban twin piston rear calipers hope this helps

No

?

Not sure

Don’t think so

Not sure on that one

Yep, you're correct.

I’m confused

Lol the pads are the exact same on either side so if you install the spring upside down it’s still right side up!

@@aydengoldsberry5721 yeah it’s a stupid ass comment no wonder. People don’t use their marbles to speak anymore.

@@garymaya1767 still wondering if these will fit my 20” Texas editions ig only one way to find out 😩

Not to my knowledge

Or the 4 piston brembo that came on corvette think 2014 not sure. Would those work

Not sure above the 07 old body style (classic).

They should because you can take the 07-19 calipers and bolt right on the front of the 99-06 trucks. Without the spacers. If these bolt right up with just washers for spacers. What would be the difference doing it visa versa.

Right, caliper bolts directly to the knuckle.

@@AutoEclinic Thank you so much for the part numbers. I looked on Rock Auto, for a 2019 Silverado, and all I can find are the 2 piston calipers.

@@jameswiz same. I cant find these

@@braydenmeals9311 I'll keep you in mind, and if I find where I can order the 4 piston calipers from, I will besure to reply tagging you, and posting the link. I'd appriciate the same if you find them, please.

@@jameswiz will do man. Im gonna check my local places too

Yes

@AutoEclinic already done and it is fantastic

Not sure, but the 07-10 have 4-pistons? The replacement shows bigger rotors yes, but floating 2piston vs 4pistion.

@@joshuabeecham2663 yep, I realized this after I made that comment. Funny that now my ‘06 is wearing a set of these now. Also, the rotors aren’t 13”, they’re 13.5”. Such a huge difference when standing on the pedal with larger wheels.

😂

Well it’s from a newer truck with different wheel designs. You can’t expect a caliper from a 2021 to bolt up to a 20 year old truck and work perfectly.

@@THEEVERYTHINGTHINGCHANNEL I was talking about the wheels. I will do it anyway. One persons loss is anothers gain. A friends uncle 2019 silverado caught fire and burned. ( catalyric converter set soem hay on fire as they were stacking bales). So I will get the wheels for cheap, and the brakes. Front only, as it was the rear of the truck that burned.

Bad move

Thanks for the honest feedback.

A lot of parts are right now

As of 02/22/23, 13545382 and 13545383 are the current caliper part numbers. If You punch in one part number at a time along with GM into the Google search bar, you will find numerous GM dealers who have them. Once I found 83, I just looked for a dealer relatively close to me with cheap shipping added it to my cart then punched in 82 and found them both one stay away just this morning.

Toyota has been using those style calipers for over 40 years with no issues

Not necessarily. If your running oversized wheels and tires you want to do it.

Oversized wheels and more horsepower seems like a plenty good reason to me.

Not sure on 17’s

If using the 22s do you need the spacer?

@@michaelsuarez720 I have an 07 Esky with 2015 22' stock rims. Will I need wheel spacers?
