Hi all, Little DIY tricks to push back pistons on electric calipers without a case or specific tools! A 12v battery and wires will do the trick! Normally it works for all brands (as long as there are only 2 wires on the caliper motor) A motor works quite simply, you have to send juice and it turns, if it is not in the right direction you reverse the wires and the motor changes direction. The trick is therefore to send 12v directly into the caliper motor and make it retract. If you see it come out reverse your wires. Be careful not to stay too long at the risk of damaging the gears (there is no electronic stop that will prevent you from doing something stupid since you are directly on the motor)
