Superforged non-integrated electronic parking brake dragging on one side

[rob99rt]

Got home from church today and found that the passenger side rear wheel had a bit of heat coming from it. Checked all the rotors with a laser thermometer and that one was 171 vs 95-100 for the other 3. Pulled the passenger rear wheel and found the outside epb pad was down to about 3mm while the inner is 6 to 7.

Grabbed the laptop and hooked it up, then tried to run the maintenance procedure to retract the epbs within forscan. Unfortunately, this failed midway through the procedure. I've got a couple codes related to that actuator now: c1034 and c2005.

Anybody ever had an issue with one of their SF epbs?

So I ran through the non-forscan epb maintenance procedure a few times to try to release/reset it (and maybe shake things loose) and then drove it for a couple minutes. The rotor was the same temp as the other side and didn't appear to be dragging any longer, so maybe??? I got it fixed? I'll drive it to work tomorrow and report back with an update. I'll still need to get another epb pad for it as it got chewed up, but hopefully SF doesn't charge a ton for it.

ETA: had to run to Home Depot and brought the laser thermometer with me, and it's definitely not fixed. EPB caliper is around 180 degrees and so is the rotor after a 6.5 mile drive, while the rest of the rotors/calipers are around 80 degrees.
