Sorry, could someone explain this again, slower and louder please.
So you have these lumps of metal that have sandpaper, like you find in a budge cage, spinning around, when a vehicle is added and brakes applied the forces generated, cause a part or to to ‘strain / move’ (equal and opposite reaction)
To make an analogue needle move.
This requires software and firmware at more than a bag of sand to ‘update’
