Installing "2021 PPV" style 6-Piston Brembo Front Brakes on a 2007 Yukon Denali

[MWD_CTSV]

Well since I couldn’t find help anywhere, I just brought the caliper to the hardware store to find what the thread size was. It’s 3/8-24 for anyone needing to know. The older banjo bolts are m10x1.5x23mm

The correct thread size is 10MMx1 for the 2022 PPV calipers.
3/8-24 is the metric equivalent of the about 9.525x1.058.

It will still fit because the diameter is smaller and the pitch is close, but it will gall the aluminum threads on the caliper under proper tightening torque. Some the bolt threads will be in contact with the upper groove, and the other end will be in contact with the lower groove (no clamping effect) and the rest will be floating. That seems very dangerous.

I went through this entire thread and did not see this question...apologies if I missed it.
The PPV calipers on RockAuto and the GMC Brembo option are clearly not the same caliper.
I'm leaning toward the PPV due to costs but the other factory system would be warranteed.
My question is... in what ways are these 2 brake systems different?

Other than the calipers, in what ways are these 2 brake systems different?

This thread is not about comparing all the brake upgrade options and it is certainly not an aftermarket vs oem. It is purely about retrofitting a pretty cool GM factory option, with only some minor compromises (offset fitments for caliper and/or wheels).

I bought the ppv calipers for my 24 escalde and was curious as to what they are made out of. They have like a plastic feel to them.

 

[petethepug]

Ahhhh, as I suspected. The PPV 6 pots may be made out of the same composite material as the 2021+ four pot calipers for the front.

 

[a4edwin]

never seen anything like that. Brembo stamp underneath doesn’t inspire much confidence.

All Brembo calipers (OEM, Performance and Racing) are going to be Aluminum. Cast or Billet depending on application. Some of the very high end stuff is a Al-Li alloy. But not composit.

>> it is certainly not an aftermarket vs oem

Apologies if I was not clear. My main inquiry is whether the GM PPV and GM OEM "big brakes" are interchangable ?
The specific application in question is a 2024 Yukon Denali that is used for towing a 7000+ lb rig.

 

[petethepug]

Yes, interchangeable on the PPV Brembo & GM high performance aftermarket. They are interchangeable. The only thing that hasn’t been clarified is if their offset to the rim & disc are identical.

Phenolic Plastic is where I was going with the odd texture on the outside of the PPV caliper. There may be a piece of it clipped on or adhered to the exterior of the caliper body.

 

[a4edwin]

Guess we shouldn’t complain considering the price paid for six pots.

Yes the calipers are aluminum not composite.

The 2021 GM PPV and the GM Brembo upgrade are very similar and probably functionally equivalent for most people. For 2024 it is a bolton. The outside diameter and the width of the rotor are the same. The major difference is the inside diameter. For the PPV the brake pad is much taller, I think mainly to accommodate bigger pistons to get a closer to stock pedal travel, but I don't know this to be a fact, because I can't find the piston sizes for the upgrade kit. So the upgrade kit should have a firmer pedal and be more performance oriented. The PPV has more rotor mass and a bigger pad, so it may be more abuse oriented. So I think either are a big upgrade for towing, but I would lean towards the bigger rotor mass of the PPV for heavy towing.

Wonder if the cost of the ZR1 brakes is worth the difference in cost over the PPV calipers. It's only $75 per caliper more, plus the cost of the adapter bracket at $225.

Great answer. Thank you.

This thread helped me a lot with upgrading to the 2021 Tahoe PPV brakes on my 2008 Yukon. I created a video to help anyone performing this upgrade in the future. My factory 20” wheels with a +31 offset did not fit (the 2021 Tahoe PPV wheels have a +28 offset)

I have searched but couldn’t find where this has been answered. Does this upgrade work 2015-2019 Yukons.

It should. GM doesn’t reinvent the wheel, which is why it fits on 2007-2014. You may have to do some slight grinding like I did, but it should work. Just make sure your wheels are at least 20” and +28 offset. I have plenty of room with my +19 offset.

 

[petethepug]

Yes it will. Thanks for posting the critical offset and tire size info.

GM doesn’t make it public but most of the suspension components in 07-14 & 15-20 (full size suv) are interchangeable by changing from a steel to aluminum knuckle and adding the 2015+ tie rod ends. Some 07-14 SUV actually have the 2015+ all aluminum front suspension from the factory.

GM also adopted the electro servo steering from the 09-13 Hybrid SUV into all other 2015+ full size SUV.

Excellent! BTW, No way I could work in the garage with stylish white shoes and not cover them with dirt/grease.
