Have you tried the suggested "fix" yet? Start the truck and leave it in park, push the pedal as hard as you can to the floor once or twice and should be MUCH better after you do that. I've got almost 10k miles on mine since doing that and the brakes are like a normal car/truck now (aside from squealing).
Why would you expect the pads to change the squeal? The compound of the pads they use is what causes it, new pads will still squeal if they don't change the material and at this point it's a safe bet they have not and will not change it. Just need to try some aftermarket pads.
I think the issue is that GM knows the pad material isn't right still and will still make a ton of noise. I intend to go aftermarket pads on mine but I'm also looking for recommendations from anyone who's swapped them out and the noise went away.
I traded my 2020 GMC 1500 for a 2020 Silverado HD with the DMAX (37k miles) back in September as I had upgraded my boat in the spring and needed more towing capacity. My old boat was only like 4k dry with a tandem trailer and the new one is 7200 dry with a triple trailer... The 1500 had a max tow rating of 9300 so I knew I was at or near it, and the lake ramp we use is at the bottom of a hill that is about 1/4 mile long and averages a 6% grade with a max of 10%, so it was a chore in my 1500. I only used the new truck to tow it a couple of times so far but it's a massive improvement. The truck is my daily, but I work from home mostly so I bet I won't put more than 10-12k miles a year on it.
I need to find an aftermarket set to stop the squeal, I don't care about paying out of pocket or doing it myself, just tired of this noise.
This is why I traded my 2020 1500 for a 2020 2500HD that is loaded.
One of many, but a 300blk suppressed.
There was another thread about this... Go out and start your truck but leave it in park, push the pedal to the floor hard, all the way then remove your foot and let the pedal come all the way back up, two or three times is what I did. This fixed the issue for me as well as others.
I picked up this 2020 2500 HD with the Z71 package and it's going to need tires in the next 5-10k miles... not sure if I'll have the funds saved up for the level and wheels before it needs tires so I'm wanting to know if it would be possible to put 35x12.5 tires on my stock wheels and not rub on stock suspension?
I just upgraded from a 2020 GMC 1500 to a 2020 Chevy 2500 HD Duramax and love it. I made the move as I have to tow a heavy boat/trailer, it's only 23' boat but it's 7200# dry but with it and the trailer I was pretty much at max of the tow rating on the 1500 and now it's like the trailer isn't even there.
No idea what the market is like in your area, but last week I traded my 2020 Sierra 1500 X31 with 16k miles for a 2020 2500HD Silverado and got $48k on the trade for my truck... they have it listed on their site for $54k now. I had an offer of 49k from another dealer but their truck was 6k more than the one I found so not a bad deal. Basically I drove the truck for a year and 16k miles and it cost me $1500 total based of what I paid for it. No break in advice though, since my "new" truck was used.
