Loss of redundancy on high voltage disconnection signal.
When EPB was applying the current measured went above the max no load current before piston position estimate predicted it would.
EPB measure current greater than max no load current before piston position estimate expect it would.
EPB may have debris blocking it from clamping correctly.
EPB releases no-load is measured using derivative of current. Currently in ghosted alert.
No-load current suggested the EPB was not in no-load causing release to continue.
EPB may not released far enough causing drag on rotor.
