Help! A6 2007 rear calipers!
 

Help guys!

right so thought I’d change the rear pads on my Audi. So I borrowed a Sealey OBD tool from a friend n started working on it.

stupid mistake I made was that I didn’t release the Park brake before starting the job. Anyways after messing with the obd tool I ended up pushing the piston out! But before it came all the way out I managed to stop the system. Now I can’t get the Caliper to make the piston back in, and now have a fault with the Park brake highlighting the Caliper I was working on!

please help a guy who thought he he could fix brakes and control my 3 kids at the same time from completely messing up the car!
