How to do a Rear brake job without the need of a Vag Com 2012 Audi A5 HD

The electromechanical parking brake is a 12-volt motor that engages and retracts the rear brakes. To retract the rear wheel parking brake, you will need access to a 12-volt battery and two jumper wires. One of the jumper wires should have an insulated clip on the end so you do not short-circuit the wires. When you are looking at the caliper you will see the brake line and electric wire/connector going to the rear caliper. Disconnect the electric connector from the caliper. Inside the connector on the caliper side you will see two medal pins sticking up. Connect the two jumper wires to the 12 volt battery. Take the negative wire jumper and connect it to one of the pins on the caliper. Then take the positive wire and touch the other pin without touching the other jumper wire and causing a short. If the caliper piston starts to push out, stop!, reverse the jumper wires. You should hear the parking brake retract and the piston not move. Continue until the caliper piston starts to spin, stop! Now push the caliper piston back in with a brake tool, c-clamp, etc. Replace pads as you would normally. After all the brakes have been replaced. Pump brake pedal until you have a firm pedal. Check the brake fluid. Then turn on and off the electromechanical parking brake a few times and you should be good to go. Very simple!
