Default Tesla Brembo Electric Parking brake

I picked up a pair of electric parking brake calipers from a Tesla to use on another project, but after tearing into these, it seems like it could be a very simple and cheap parking brake option for anyone with different brake setups out back...
Anyway, there is a 4 pin terminal on each caliper, 2 of the pins are the motor wires, the other two seem like a temperature sensor (ohm reading between the two pins rises/falls with temp)
Im sure the Tesla has some kind of current sensing algorithm in their BCU that says x Amps = x clamping force but for simplicity I think im going to just use proper judgement with an amperage "overload shutoff" so that if I did hold the switch too long it would cut power to prevent burning something up. Does anyone know of any off the shelf parts that could accomplish this? I did some googling but Im not too sure I know what Im looking at with some of these current shutoff switches.

BTW, I paid $114 shipped (for the pair!) on ebay. If you have the depth needed for these calipers its a very economical option compared to the mechanical brembo spot calipers (not even sure where to get those) or the IPSCO calipers. They are setup for a 1.1" wide rotor, but its a split caliper, so a simple spacer could get it over a 1.25" rotor
