What was new for me this time around, was electronic parking brakes.
This was an '18 Accord with those electronics on the caliper. The "normal" way to change the brake pads is to connect to the computer and tell the vehicle brakes to go into a maintenance mode, which will retract the parking brake gearing fully. Then when complete, take the brakes out of maintenance mode.
Not having that capability, I watched a couple YouTube videos, and they showed a method to disconnect the electronic brakes, remove the e-brake assembly from the caliper, and manually wind back the gearing to a fully retracted state. At this point, I was able to push the caliper piston back just like a normal caliper. Another method is to screw the piston to unwind the e-brake gearing and allow for piston push, but the typical auto-store tools did not fit this piston.
After that, changing the pads was just like any other vehicle. When we were done, had to turn on and off the parking brake a few times to let the gearing fully engage the pads.
