PMDG 737 Parking Brake Issue

[gear_d0wn1256 6]

Wondering if anyone has a similar issue. With any PMDG 737, I seem to have issue with the parking brake. I know they updated the logic to reflect the actual aircraft (depress pedal brakes and then release parking brake lever). However once I push back from the gate, or try to disengage the parking brake again. My brakes do not depress, and I cannot disengage the parking brake. I've tried keyboard commands, joystick commands you name it. I have no luck. Randomly the brake will finally allow me disengage. I have ZERO failures and turned off maint' intervals in the PMDG FMC. Any ideas? I don't use rudder pedals.  *This is specific to MSFS2020*

Just out of curiosity, have you tried it with no keybindings on any device, and pressing it in-game?

You might have to go into the maintenance menu in the  FMC and top-up the brake fluid (or whatever the label is) I've experienced a situation where the flaps wouldn't extend for take off, I remedied the problem through the aforementioned maintenance section.

I have not. Although that's not the issue so it seems.... I actually lose my pedal brakes for what seems to be minutes on end (can see in the VC, they do not even move or actuate), therefore I cannot even click the parking brake using a mouse and no key bindings to release it per the real world logic thats integrated.

 It's every single flight, and I also have Failures and Service Intervals turned off in the FMC PMDG Menu. That's why Im scratching my head. And EVEN attempting to use PMDG Maint service all fluids does not work.

I had the same issue and couldn't find any solution. Solved it removing rudder and brakes axes from FSUIPC and assigning these axes in MSFS. So FSUIPC was the problem here. If you use FSUIPC you can check it.

I do not use FSUIPC so I'm baffled.

I find that when I press the brakes using the rudder pedals, if I don't press them all the way ( like 100% braking, ) the parking brake will not release. Check  your calibration for your brake pedals, and make sure they go to 100%

I have a hard time pressing my pedals full for long enough to engage/disengage the parking brake.  The workaround I read elsewhere is to assign a key to wheel brakes (I use the . Key for nostalgia) and press that when you need to release the brakes.

No troubles here, FWIW

That one change to the brake has made the PMDG 737 totally unuseable on my sim.

Why is that?

Post this on the PMDG forum.  https://forum.pmdg.com/forum/main-forum/pmdg-737-for-msfs

I had this problem. Then I used the Toolbar Pushback button to unlock the brakes. Then, later, the problem just went away.
