The caliper is driven by an electric motor. Straight forward enough.
But to change the pads requires a lap top and the caliper has to be dismantled.
Much better way.
About 15 years ago I designed a motor driven handbrake for a disabled guy. But unfortunately he died before the conversion actually got done.
The design had a lead screw driven by an electric motor. The lead screw pulled the handbrake cable. To get proper tension on the cable the motor body wss free to rotate against a strong spring. The rotation of the body caused a contact to open thus working a relay to stop the motor. When stopped the motor is live both sides. Depending which wire is earthed like shadow windows.
No lap top or caliper strip down to change pads.
If someone fancies making one. Get a lead screw from a jack. Wiper motor and gearbox. Wiper motor must be permanent magnet type. Most are nowadays.
