PS5 Class 350/1 Brakes

hi all I'm doing the scenario contingency measures and I'm at Birmingham new street and my now lead unit has frozen the brakes at BC 3.0 and will not release no matter what i try and it's driving me nuts!!! the now rear unit remains fine and is drivable upto the red signal in the rear.
DTG Matt is there anything in the pipeline to fix this as I've tried everything

 

i have had all safety systems on and off and it's on the Birmingham to crew route jamie

 

This is an issue that exists for ages now. So its reported many times already. Hopefully it will be fixed....
