I have now tried it in the 757-200ER PW in P3D v4.5 (4.5.13.32097), and the parking brake is working fine for me, *regardless of whether EP/EA is in use, or the APU is ON or OFF. :-/ *When I tried it in the 757-200ER PW in FSX, it worked. However, without EP/EA, or the APU OFF, it worked 5 times, then stopped working. With EP/EA in use, or the APU ON, it worked continuously.

Still no joy with me. What do you mean by EP/EA? I have tried every -200 variant with same results, i.e. parking brake inoperative by mouse clicking but CTRL+. sequence by keyboard does. I should have emphasised that mouse clicking on the park brake is not working correctly whereas the standard keyboard sequence does.
