This thread has the all the information I found to be relevant for upgrading to 6 piston Brembo calipers on a 2007-2014 generation model in the most cost effective way possible. There may be small differences here and there, but you'll get the idea. For reference in the pictures my calipers are already painted Silver, but that was DIY, these caliper ship non gloss black.

These are the largest brakes available using OEM parts. The rotors come in at 410mm. This setup is basically the same as the GM Performance Brakes upgrade via PN 85138043, except the calipers aren't painted red, and the design of the caliper is slightly different. It's also 50% of the cost coming in at under $1200.

This setup was used primarily on the 2021 Tahoe PPV, but it appears to be some kind of option on 2021 Escalade 3.0 Diesels based on part fitment data. Differing from the GM Performance setup, these calipers have a larger cross brace on the top

I used all OEM parts, except the pads and rotors as they are available much cheaper in the aftermarket.

I did not change the dust shields but I will when I eventually do a wheel bearing. The stock dust shields worked without modification.

Wheel choice is going to be a big variable. GM says 20 and 22 OE wheels will fit the brakes, from a diameter perspective. It's going to be in the offset and the design of the spokes that things can cause problems. Here they are fitted to a set of '12-14 Escalade 22" wheels which have 31mm offset and they clear with ease. I'll have another test coming with 27mm offset 20" honeycomb wheels.

In the middle of the install of the 2021 Tahoe PPV 6 piston Brembo front brakes on my 2007 Yukon Denali XL. So far everything is fitting perfect. Just have them bolted up for a test fit and they clear my Escalade 22s with ease (offset is 31mm). I have a set of 20" Sierra Honeycomb wheels arriving tomorrow so I'll follow up with the fitment on those (offset 27mm). Hopefully will have time tonight to finish the install and bleed the brakes.

Here are some pictures so far. I did paint the calipers silver instead of the black they came in. Pads are still on the FedEx truck so no pads in there yet. Might have to install a shim to center the caliper, unknown until I get the pads in there.
Are those the ones that are labeled heavy duty on rock auto for like $350 a piece

On my 2007 a thin fender washer was needed to center the caliper on the rotor. The washer is about the thickness of a dime with a 9/16" center hole. My hardware store didn't have the right size in the thickness (thinness) that was needed so I got thin 3/8" center hole washers and drilled the hole out with a 9/16" bit. Worked perfect.

The bracket on top of the knuckle needs to be bent ever so slightly.

The stock brake hoses fit perfectly fine using the banjo bolts and crush washers listed.

Here is the parts list:

Calipers:
GM 84793057
GM 84793058

Pads & Rotors:
Power Stop 172407
Dynamic Friction 604-47079 (2)

Caliper Mounting Bolts:
GM 11612265 (4)

Banjo Bolts & Crush Washers:
GM 11569590 (2)
GM 21012386 (4)

Misc:
Fender Washer (4) See Above
Backing Plates: 84763235/84763236 (not required)

Sweet! What year Escalade 22" rims are those?
Thanks.

2012-2014. GM part number 22755314.
Thank you!
I ask, because other than yours are polished/plated, those are the 22” rims on my 2013 Escalade ESV Premium.
I am taking notes from this thread for future reference.

Nicely done and worth of a sticky if I say so myself. Hopefully GM will continue down this road and offer a bolt on kit for the rear brakes.

Until then, there is a kit available to add C7 Vette calipers to the rear using the OEM discs.

Here’s the link from the EXT the kit was put on that’s adding a little hp upgrade.

The Sierra Honeycomb 20" wheels clear with ease as well. There is more than a fingers worth of room between the spokes and the caliper.

Hi from my knowledge you’re using the 6 piston wrong rotor for that set up. I did the ppv calipers too but I order oem ppv rotors no one made them 1 year go when I did the swap. But now power stop makes them and raybestos and gm discontinued the #84865905. And the rotor you bought are for gm brembo 6 piston upgrade kit that use 16” rotor not the HEAVY DUTY ppv. The braking surface is different from 2.5” to the ppv rotor being 3” and how I know because I bought Dynamic Friction 604-47079 but to do the ctsvbrakeswap.com zr1 brake conversion and I compared both they are very similar. I’m sure you won’t have problem just that your pad probably over hanging and not making 100% contact.
