I did the same thing and managed to rebuild the calliper eventually after a got hold of a new Circlip to replace the broken one. They are called a wire lock with tang not a Circlip. Have a look at this video and forward to about 2.20 mins into the video.https://youtu.be/ohbIFfdZJOo?si=faaoHdF3b6hxxqT6

That is correct Noodle. The circlip goes on the threads as shown. Make sure to rotate the circlip all the way to the bottom of the threads under the black mechanism. And the end that sticks out must go towards the end of the bolt to ensure it sits in the slots on the female end. It was a bit difficult, but I used a narrow screwdriver to continue to rotate it until it bottomed out. If you do to rotate it all the way it will not allow the piston to retract far enough into the caliper to allow the caliper to fit over the new break pads and you will need to repeat the process of removing the piston (after it has been pushed all the way to the into the caliper) and reinstall it.
After reinstalling the calipers I had an issue in which the EPB would not disengage on the tire in which I replaced the break so I had to follow the below video in which I took the EPB motor off, rotated the hex nut 2 full turns and re-installed the EPB motor.

My former mini cooper forum had tons of people helping me out from A to Z but of course the minis were always having problems so people were experts at fixing everything ha ha ha .
To answer your question concerning the wire lock ......I kept my old brake caliper that I replaced 5 months ago and took it apart to reuse the wire lock ( wait and see now youll have people telling me that I should not have reused it .......)
otherwise I had no.idea where to find the wire lock.. Autozone, oreyllys...junk yard ..didnt have it ....maybe a dealer has it ....not sure..Worst case Napa auto parts sell the caliper for around $150 ish .....better than Mazda $300
((((I wish you the best of luck
