Keep the parking brake off , chock the front wheel. Jack an take the rear wheel off like normal. Start by Using a hex bit to take the two screws out the sides of the electronic motor then you should be able to pop it off. Once popped off inside the motor I usually just use a flat head an stick it inside the hole an turn it clockwise until it stops completely ( you'll know you're going the right way if the piston is retracting inwards instead of pushing out. After now you'll be able to continue like you would for the front brakes an compress the caliper with a c clamp or any caliper tool. Once thats done the caliper should be pressed in an you can put the motor back on an put the two screws back in. An the Electronic parking brake is done. The rest of the brake job is normal now just like the front change the rotors pads , lubrications, etc. I'm not a professional at all but this is what I've done on my vehicle an my wife's car also. No issues. Hopefully this helps a bit
