Today I was driving an EC service and made a routine stop at a station, however when I went to depart and put my service brake back into the running position, the brake hose refused to drop below 15%. I tried various positions of the brake lever, including fill, disabled, as well as putting it back into initial and attempting to release again. I also tried the brake releaser button. Nothing worked. I was able to apply power, however the brake pressure was sufficient to prevent me from moving.
I have found similar topics regarding brake release but not this issue exactly, so I'm trying to figure out if I did something wrong or if it was some kind of bug.
