Brakes squeel like crazy

It’s the PPV pad material, backing, etc. Live with it, try to have the dealer spray the pads with CRC Disc Brake Quiet, or swap out for a different set of pads.

Quick question about the brake squeal…

Is it noticed right after placing the vehicle into service or is there a window where the issue starts to develop after a period of time?

After a slow start getting our 2023 Tahoes upfitted, we are now placing them into service. I haven’t heard of any complaints (yet it seems) about break squeal.

Noticed our 2022’s started the squealing when they hit about 1500-2500 miles.

Hey everyone, I'm a Fleet Tech for a local municipality. The brake squeal in the gm ppv is not a new problem. We have delt with it in every gm police car since 04. The factory gm pads are just noisy and wear out fast. We deal with the sqeal until the 1st brake job and swap out to another pad. We have had really good luck over the years swapping to Rebestos Police specific pads and rotors. No sqealing lot longer wear intervals depending on the officer.

Point is I have (10) 2021 tahoes , (6) 2023 tahoes. All of our 21's squeal and haven't got more than 20 to 22k miles out of original pads all 4 corners depending on driver. We have been doing fronts at 20 and rears at 22k. We have since replaced all of these with the Rebestos Police pads and resurfaced the rotor.

The numbers I wil share are for the 16" front rotors and 6 piston calipers with the 13" rear rotors. So far, O'Reillys is the only one for us that can get these. Front pads are # SP2407PP
Rear pad # SP2174APPH. O'Reillys does off the replacement rotors as well.

There are different manufacturers of good police replacement pads. These are what has worked for us over the years and have worked very well, so this is what we stick with. We have used this brand in 2004 to 2013 Impalas, 2000 to 06 tahoes, 2020 tahoes and our current 2021 tahoes. Hope this information helps.

Thanks for the parts information. I’ll pass it on to our techs.

With our fleet of 2023 Tahoes, they all made it to about 4,000 miles before the brake squeal started. It can be quite annoying.
