Front brakes dragging after changing

[Dave78]

Hi everyone, I have a 2019 sierra AT4.  Has about 70000km on it and the rear brakes needed to be changed so I did both front and rear pads and rotors.  Everything seemed to go smoothly, and I got a bunch of the ABS codes on startup that I read about.  I cleared those codes and things seemed better.   After going through the brake bedding procedure, the fronts are now dragging to the point that they're smoking when I stop. Any idea what could cause this?  Doesn't make sense to me as there's nothing to be binding with this new caliper design.   Thanks in advance

did you reset the brake wear monitor

[Dave78]

My brake wear monitor had failed prior to this.  Was displaying "service brake monitor" so I just disabled it.

Interestingly though, after I left the truck sit and cool down for a couple hours after the test drive, everything went back to normal and it's good to go.  Very puzzling but happy with the result.

What frosts me is that I had to replace all 4 rotors on my 2020 Sierra SLT with 36,000 miles due to pitting on the rotors and warped rear rotor. Garbage steel for brake rotors, probably made in China or Mexico. Had to replace them on my wife's 2019 Equinox with 24,000 miles on it for pitting also. Going to have to rethink buying GM, have bought new trucks every couple years for the last 30 years. Might be time to rethink them.
