How to get active parking brake

Anyone know how to get good parking brake? I want the motor to actively resist any movement. In FOC mode, the braking is just nonexistent in the lower speeds. BLDC mode braking is a lot better - but the motor doesn’t spin very well in that mode. It can’t detect the hall sensors (which it can in FOC mode) and so it only goes sensorless and makes the motor louder than when spinning in FOC mode. I’ve heard that the kind of braking I’m looking for is achieved by shorting the 3 motor phase wires wh…
