so i was doing the rear brakes on my 2013 bmw 528i and i followed intructions on how to back off the caliper without any scan tools , i took the big electronic part off and started moving it clockwise then i guess i over did it and heard a snap , now the caliper moves freely , i know its broken i want to replace it but i cant find any intructions with pictures or videos to go off by i really dont want to trust ai but its seems like its my only choice right now im probably going to buy the part tommorow but i need to find any instructions on how to do it

please help thank you
