Anyone have any updated information on replacing rear pads and rotors on 19 GMC with EPB and pad sensors?

I tried this procedure and it only put park brake on when I held pedal and button for 10 seconds. Did nothing when I took foot off pedal and hit switch.

1. Engine OFF 

 

2. Electronic parking brake also  OFF

3. hold the push-to-start button to get accessories mode on. Or if you have the key ignition   turn it half way before starting the engine. 

 

4. hold brake pedal and electric parking for 12 seconds  then let go at the same time.

 

5. quickly press the electric parking brake button once more then let go. 
 

you should be in the brake service mode after a couple tries. You’ll hear the noise and the yellow light on your dash blinking etc. 

 

 

Only after you do this then change your brakes in the rear. I was easily able to push in the piston and install my news pads. 
 

if you remove your brakes and caliper first then do this procedure your piston will fall out and it’ll take you hours to get it back in without damaging the the seal. Ask me how i know. 
 

POINT BEING IS get the truck into brake service mode first THEN doing the rear brakes is to easy.
