Brake rotors

Dave Sullivan · September 7, 2022

Anyone having issues with their disc brakes? I have 32,000kms on my truck and three of the four rotors have deep gouges in them. Dealer says it is from sitting and rusting but my truck drives every day. Just wondering if anyone else has this issue. The dealers say it is not under warranty.

I drive a 2019 Chevy Silverado Custom Trailboss 4x4.

Usually that happens with bad pads or something gets stuck in the pad like a rock. It then wear a groove into the rotor.

And yeah, it wouldn't be covered under warranty on a 2019 because of the year. If it bugs you, you can replace the rotors and pads yourself or just wait until you get more miles on them.

This is their "go-to" answer. They're full of it. I have a 2019 AT4 and there was apparently a TSB out for uneven pad wear....The solution was to replace the pads and rotors, no other explanation. Part number changed completely as well...so I'm leaning towards the fact that the pads and or rotors were garbage that shipped with the trucks, maybe poor material or something.

I was never offered this for when I had my brakes checked. I've attached a couple of photos for you to compare. You can see how mine was embossed, not a groove. The pads had a groove in them, but the rotors had material raised. Which is not rust or a valid answer.

My friend who is a GM mechanic told me their standard answer for this issue is exactly what you said. I told him the same, I drive daily, truck does not sit. Basically it's a bullshit answer.

I ended up replacing my pads and rotors and I only have 57,000kms, never towed or had heavy loads in the back.
