PMDG 737 Parking brake releasing

Can anyone tell me why the PMDG 737 NGX parking brake keeps releasing itselft at the end of the pushback

Hardware spikes. Check your hardware brake axis for errant signals.

As above. If you're using something like a Saitek set of pedals they're notorious for spikes. Pushing the brakes knocks the parking brake off, sometimes quite noisily. It's poor technique. It's far nicer to leave your fingers under the park brake and ease it down when you push the brakes to release.
