Brembo or PPV Brakes on 21 Tahoe.

[nodnarb901]

Recently purchased a used 21 Tahoe.
I have seen the Police PPV calipers and even used 6 piston GM Brembos for sale for a reasonable price.
In addition to the calipers I assume I would need new rotors? Do I need to buy new backing plates/dust shields or any other parts?
Can I used the same brake proprotioning valve and Master Cylinder?
Are there any threads detailing this install?
Is this even something I should consider?

You'll need 20" front wheels too.

 

[MarvinVR]

Oh dang---20s? There goes that project.

 

[nodnarb901]

Thank you for the reply, It already has the 22" wheels on it as it is a high country model. I may look at changing the wheels if I do the brakes to show off the calipers if I do this.

20" OR LARGER, right?

I think your best bet is to check out the kit online and see what all is included with the stock kit. If those other things aren't included in the kit -- and the description doesn't say that it requires additional parts that are not part of the kit -- then I think it's safe to assume that the kit is essentially bolt-on with your other components.

I think you WILL need new rotors, though (and the kit should say that).

Thought it went without saying ... but then I thought, if someone wondered for any length of time,
'Will they fit inside my 22" / 24" / etc wheels?', it'd be interesting.
So I left out the qualifier, on purpose, because I'm a lazy sadyst.

“Sadyst”? Lazy speller, too. But hey, at least you’re honest. Lol

I agree, it SHOULD go without saying. But, well, you know…

es ey dee eye es tea. I - of all people - know it and its spelling well.
This forum's asterisk humbuggery forces various sundry misspellings, gottdamnt.

3 types of $@di$t:
1st, most think of as dangerous, and rightly so, unless put in check early in their development.
2nd, make m@$0ch!$ts VERY happy; many of these used to be of the 1st type.
3rd, lazy ones ... cause m@$0ch!$ts great pain, by being very kind patient and courteous. Think Amortycan Grickfitti.

How big is the spare on the newer suvs? The reason I am asking I ran into an issue with my 2015 Yukon Denali with the brembo brake package. The spare will not fit over the front flat tire. GM response was to do a two tire change. Example remove the rear tire first place the spare on the rear take the rear tire and rim place it on the front to go over the Bramos.. I hope this helps. I also have the service bulletin if you want to see it

Yep, that's the response -- or make sure that the spare you carry is a 20"+ too.

I tried to put a 20 inch spare in the space where the 18 goes it will not fit at highway speeds. It starts to vibrate way too much so just be aware of that.

Two things color my opinion here:

I have a '22 BMW 540i with the Brembo upgrade. They only work well if I'm driving like a total *******. But when I drive like a normal person using less than moderate braking, they suck. They squeal like a pig, grab hard when not hot, and are completely incapable of being modulated in the smooth manner that my passengers expect out of me. Truly awful, especially when compared to other BMWs I currently own. I 100% regret choosing that option. In the low-percentage chance BMW produces another car I want, I will definitely not pick that option.

So, when I talked to my dealership about ordering a new Yukon (prior to learning I could not pick options with the LZO motor), we discussed the Brembo option. He strongly discouraged me, as most of his customers complained about the noise.

So, I might consider the PPV brake set up, but not the Brembos. Really a shame, because I loved the Brembos I had on my motorcycles.

 

[petethepug]

Google best sums it up …
“GM PPV (Police Pursuit Vehicle) front calipers are actually
Brembo 6-piston fixed calipers paired with large 16-inch rotors, making them a popular, cost-effective big brake upgrade for other GM trucks/SUVs, offering superior stopping power and heat dissipation compared to standard OEM brakes, with specs like ~410mm rotors (vs. stock ~12-inch/300mm), significantly boosting safety and towing confidence. The main difference from aftermarket Brembo kits is cost and color (PPV are black/grey, aftermarket often red), not fundamental performance.“

It's the pads. Find pads you like better.

Tire Rack is a decent place to look.

I am going to do the PPV brake swap this spring on my 2021 Suburban but will be using other pads. The stock PPV pads are semi metallic, better braking, squeakier and dustier than a ceramic would be. I am slowly gathering parts and when it gets nicer out, April time frame, I will be doing the swap.

Than is when you buy a full size grown up 20 or 22 inch spare wheel and tire

Only problem the spot for the spare only fits an 18 inch.a 20 inch causes terrible vibration at highway speeds. So unless you want to use up cargo space and carry it inside

What about a 20”+ doesn’t fit and/or makes it vibrate? I’m trying to picture what the issue really is.

Uh, the spare should be the same tire height as what’s on the vehicle, so the wheel diameter has ZERO to do with fitting where the spare resides.
