Add me to the list of folks cursing at the parking brake...

For those who have done the job using maintenance mode:

Do you need to return to normal mode (without engaging the e brake) before bleeding the rears?

I'm replacing brake lines and pads at the same time.

I understand the part about bleeding, cycling the ebrake 5 times and bleeding again. I'm asking about before the first time you bleed.

Hmm that a good question. What I’d do is the first bleed, then take it out of maintenance mode and activate it 5 or so times and bleed it again until air stops coming out.
To be extra safe you can turn it off once more, but probably not necessary

Do all honda’s with electric e brake use this same procedure? Compress the piston on the caliper once it’s in service mode? Thanks

All vehicles in general with electric rear calipers are done this way. The motor is there to spin the piston. (A spindle that drives the piston, actually) That’s what the service mode does.

Here's an idea
From now on don't put it in maintenance mode period. Just go to autozone and rent the brake kit and use F and turn it clockwise until it bottoms out and replace your pads. Get her back on the ground and engage the e-brake 1 time and done with no issues.

Using a scantool to unwind the ebrake motors just prevents you from having to do it manually by removing each motor and turning the shaft by hand. Either way you choose to unwind the motors:

1.)Unwind the motors with scan tool OR remove and unwind by hand.
2.)Disconnect motor connectors to prevent damage.
3.)Replace pads/rotors.
4.)Compress caliper pistons.
5.)Re-install calipers and motors, re-connect motor connectors.
6.)Pump brakes to build pressure.
7.)Bleed brakes
8.)Engage parking brake for the first time OR use the scan tool to take out of maintenance mode and electronically spin motors back.

And don't forget
9. Engage/disengage PB 5 times
10. Rebleed back brakes.

I use a positive pressure system so no need for me to pump brakes prior to bleeding (whole lotta air to clear with new lines).

My only question was whether bleeding prior to taking the brakes out of maint mode (but before first parking brake engagement) was a waste of time. It looks like you say no.

can someone explain the purpose of rear brake bleeding if it has not been exposed to air pockets?

No reason whatsoever. Nor has anyone suggested so in this thread.

Got it, missed the part you’re doing brake lines .

Besides this guy yesterday lol

After new calipers and actuators, car is mobile again.... won't make the same mistake twice. Thanks for the insight and guidance, all.

Did they confirm it was the shaft that was broken?

No confirmation on the shaft being broken, they started with actuators which didn't make a difference, once the calipers were swapped everything worked.
