Looking for assistance on the rear brakes on my 2019 q7. Trying to change rear pads. Caliber came off fine (did not use a scan tool to release pressure as I’m now leaning I should have). Installed new pads and now I’m unable to get caliber back on. To make matters worse the EPB has now pushed out further and feels as if it the rod has disconnected from the EPB motor. I tried to push back into place however it is just pushing oil out. I have a scan tool ordered to pull it back in however I fear it is disconnected the rod from the motor. Picture is looking from the floor up to the EPB.
