4 Piston Big Brake Upgrade from 2019-20

So I see guys on youtube doing this 4 piston upgrade from a 2019 silverado to their 00-06 silverado. Has anyone here tried this on the Tahoe? Should fit right? Seems pretty easy and straight foreward. Like $350 in parts. I would like bigger brakes.

As purchased,

Primer.

Painted.

Better brakes all around, easy to service the pads, the caliper is lighter, and the brake feel is improved. I had new set of brakes on the car when I purchased it so I am not comparing new vs old but I think the upsize of the rotor and the increased pressure from the 4 pistons helps to make the pedal feel firm and inspiring. My old brakes probably had some air in them as the pedal was always soft and did not brake well in emergency situations.

What vehicle did you do this on? Any modifications besides painting? My wife's 2015 Tahoe needs new front brakes and I'd love to upgrade. She drives like she's in an F1 race and eats through brakes. Wondering if this would help her out at all.

These brakes came on all 2019 and up silverado tahoe, suburban escalade yukons, its a standard replacement for the old 2 piston floating caliper set up. The rotor goes from 330mm to 350mm so that helps some. The caliper itself has 4 pistons so more even pressure across both pads and these should work better on your 2015.

On my truck given that it had already new pads and rotors, the breaking was always lacking and left a lot to be desired. Pedal was soft and mushy with no real confidence feel.

WIth the new brakes it now feels more firm and has a hard stop point where the brakes start to really grab and it allows you to bring the heavy vehicle to a stop with high confidence. I think this is 100% must upgrade given you can find these for dirt cheap. My set up was 150$ came off a new escalade with only 4mi on the odometer. I got rotors, pads and calipers in that package deal. Hunt market place for these, they do show up from time to time as dealers are doing factory brake upgrades on some of the new models and they simply throw these in the trash. Some mechanics will save these parts and resell them.

I hadn't even thought about looking for take offs. I see a couple near me for around $500. Not quite a steal, but a little better than brand new from RockAuto.

I just looked up the OEM caliper part numbers for my 2010 Avalanche and it's the same as my wife's 2015 Tahoe, so looks like I could do this swap on my truck too. Like I need more projects on the list.

Don't think of the front brake calipers / rotors / pads as a 'project', think of it as a maintenance update-upgrade -
you're literally installing even newER calipers pads & rotors onto your older vehicle. There is no downside.

Yeah, it's definitely an upgrade. But in the grand scheme of things, it's another item on the TODO that's 8 miles long and seems to never get shorter. Such is life.

What do you do about the sensor wire? Looks like these pads don't have squealers, but have a pad sensor built in maybe.

so I finally installed the 4-pots.
I needed 1/2" (13mm) wheel spacers to get the wheel (22" snowflakes) to clear the calipers.
I used 2 washers for 1/8" to center the caliper.

hunting for other factory wheels that will clear the calipers..20s or 22s..

Wheel spacers is one thing I'm afraid of. I don't want to have to do that. I have 22" OEM wheels, not even sure what style they are, but I'm hoping I don't have to use any spacers with them.

Although this 'fear' can be drastically mitigated by using very small spacers,
have you considered grinding down the unrequired surface area of the calipers?

I guess fear was the wrong word. Was just hoping not to use them at all just to keep the install cleaner. Grinding down is an option, although I question that some bc why was it there in the first place if it's unnecessary?

What size washers did you use? I took a bracket bolt with me to Lowe's to try to figure out what size. I was looking at the grade 8 washers and it seemed like 1/2" was slightly too small and 9/16" might be slightly too big...of course.

 

[Marky Dissod]

... just hoping not to use them at all just to keep the install cleaner.

Which is why I suggested using smaller washers. They're just washers, it's not like performing the coagula procedure.

Because it's cheaper & faster to cast easier shapes.
There are several 18" wheels (usually the older GM OE wheels) that don't work without grinding the calipers down a bit,
but the point is grinding them down a bit - start with that dumb bar where a brand name might go - opens up your wheel options considerably.

Just wanted to say the backing plate numbers above seem to reference 2500/3500 trucks.
(They look like they have an offset to them that I don't see on the 1500/suv backing plates)
The part number I find for Tahoes and 1500's are

GM GENUINE 23363947
Front Right; ORDER W/ BEARING O-RING PN 23390381 QTY 2; FRONT & REAR Disc Brakes w/ ABS(J61)

GM GENUINE 84926922
Front Left; FRONT & REAR Disc Brakes w/ ABS(J61)

Not sure what the O-ring is about..
(when I search for 23390381 on RA, I get GM GENUINE 290307, a 3.5mm thick O-ring apparently.. )

07-14 dust shields clear no problem anyhow, so '15+ probably do as well.
sorry wrong year forum.

my 2016 Tahoe.
I did not use the dust shields from 2019 Silverado. the factory ones were just smaller than rotor diameter.

stainless steel braided lines as well...noticeable brake performance.

I also got drilled & slotted rotors for all four corners.
