2023 2500HD front brakes

[Jimmy in NC]

I have been fighting with warped rotors for the last 25,000 miles and have had enough where I will fIx what GM said was not an issue under warranty.  I have done a ton of disc brakes over the last 40 years but someone mentioned that the ABS on these new trucks will not allow backing the calipers up.  Any truth to this?  Also if I simply replace the wear sensor will that rest the wear indicator on the dash or is that a plug in and reset the computer deal?  When installed anything other than pump the pedal and fill the calipers before starting or is there some pressure build procedure as on the half tons?  Have searched and plenty of info on the half tons but nothing on the bigger brakes. Any help is appreciated.

"Backing the calipers up"

what is that?

Compressing the calipers to install new pads.  I know some of the newer ABS systems do not like moving that much brake fluid "backwards" as the pistons are compressed back.  Trying to figure out if this module is one of those or if I can simply compress the pistons as always normal and move on.

GM states the following:

 

1. Inspect the fluid level in the brake master cylinder reservoir.

 

1. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.

 

1. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed before proceeding.

 

As far as computer stuff, the HDs don't have the parking brake on the caliper, that's on the 1500s.

 

Wear sensor, it may or may not reset itself, if it doesn't, needs a scan tool to perform the pad life reset.

Thank you for the clarification!
