What kind of defining issues can arise from performing this procedure without using the brake maintenance mode with a scanner. There is a vague description above that may not calibrate properly and may cause problems in the near or distant future with brake pull. Can you provide more context than that? What did the specialists specify as risks? Why would these mechanism failures occur?
I ask because the rear EPB is identical in every way that I can see to the 5th gen outboard and late Foresters which have a passage in the FSM on how to pull the piston without the scan tool. I understand that this snippet does not exist in the Ascent manual. In my experience, both online and researching, the EPB hardware and functionality is the same for our Ascent as the 5th gen outboard.
I remember you answering in the past, that while the hardware is the same, these are considered different, how exactly are they different? Finally, I completed a rear brake pad replacement on my 2019 Ascent last week without using the software scan tool. I followed the 5th gen outback procedure:
Disconnect the negative battery, disconnect the EPB harness behind the caliper, remove the caliper mounts (7mm hex), pull the piston rotating clockwise, install new pads, grease in suitable places, reassemble. Double check the work.
I locked all the buckles, pushed the brake pedal a few times, then engaged/disabled the EPB about 10 times. Everything works as it should, no drag, and is engaging/disengaging just like it did with my old pads.
My question is: what could go wrong and why?
Thank you with respect,
