Will be doing the '19-'21 Big brake upgrade on my '00 Tahoe.

Hello all. Just got my Brake caliper and pads for the big brake upgrade. Hopefully this coming weekend I can get started on it (still waiting on rotors). Never knew how hard it was to get my hands on these. Everywhere was sold out or labeled "discontinued?". I got lucky and was able to score a set. Hopefully these will make a bit of difference over my squishy factory setup. Also I am preparing to do the vacuum to Hydroboost swap (I was going to do that first but I was having such a "where's waldo" moment finding these calipers that I jumped on them when it became available as I probably would never get another chance at it.).

As far as tires go I am currently running Vision Legends 17" wheels. I did a test fit and they just barely clear. Eventually I will be upgrading to 20" wheels.

Will keep you all updated.

What do you mean by "vacuum to hydraulic brake swap"?

Sorry I meant to say Hydroboost conversion. I made the correction!

Where'd you find the calipers??? Been searching for over a month? Junkyard?

Ok I finally got done with the swap. Took forever as my Rotors I ordered from RockAuto got delayed in Illinois for close to five days for some reason. Anyway here are the picks. I will start by answering some questions I hope you may have for me.
The swap out was almost straight forward, However I know everyone heard about the caliper needing adjustment after install as the outer rotor will most definitely hit the inside of the caliper making the rotor impossible to turn. Now I will tell you what I did. I used a 1/8 thick shim in-between the inner caliper and knuckle to move the caliper over. To my surprised it damn near centered the caliper allowing the rotor to rotate.

Did I have to make any other adjustments after that? Nope that was it. other then that it was plug and play (at least for me). Please note that I am using aftermarket steel braided lines but they are suppose to be factory length (can't remember where I got them as they are about 3 years old) so if anyone is running rubber lines it still should make it to the caliper without issues.

My wheels are Vision legends 17" rims. I have a good amount of space between the caliper and the rim without needing spacers or grinding a bit of the caliper down. So I got lucky.

Any difference in braking? Short answer...yes. Then again my brakes were 20+ year old OEM. Even bleeding them and getting better brakes and rotors (before this upgrade) changes were uninspiring and still squishy. This setup is firm and noticeable. I have yet to do any hard breaking as I'm still bedding in the new brakes but even light normal breaking I notice a huge difference! Actually the difference is so noticeable I may not have to go hydroboost just yet.

Also for anyone who is having a hard time finding these brakes I was doing some research and ran across this site https://ctsvbrakeswap.com/ They sell brackets that will allow you to retrofit six piston (front) and four piston (rear) Corvette brakes to your Silverado and Tahoe. Also here is a site that sell Hydroboost kits for those of you who want to buy new. https://www.powerbrakeservice.net/ Just be warned the prices will make you want to dive through a salvage yard but I am placing it here anyway in case you are interested.

Thank you for this! I drove my daughter's Suburban 1500 a few weeks ago, and the brakes are squishy as a gummi bear in Texas heat. This is in comparison to my other daughter's 2003 Sierra Denali, my 2004 Silverado 2500, and my wife's 2005 Suburban 2500.

Drove 10 hours round trip to get a set out of a junkyard in Virginia!? Now just gotta get them painted & then install them!
