My slight attitude and my comment about you trying to be funny came from your wishes that my own car needs brake work just after the warranty is out. Is that really how one should answer a question?
That's water under the bridge, I'm not hurt nor do I believe you should care if I am or not. Maybe we just had a simple misunderstanding but regardless it worked out.
For the topic of discussion, I'm experienced in brake repair but will freely admit that up until the salesman told me about the "hill hold" button, I had never heard of an electric parking brake in my entire career. Your thread and pics have helped some with that and I'm grateful for your effort to reveal the system.
Something I'm a bit embarrassed to admit, beyond repairing the brakes when something wears out I've never heard of routine maintenance on brakes. The information you provided showed me there can be things done to help the longevity of the parts other than simply waiting to hear the wear indicators start wailing. Indeed I feel like this thread should be a part of the maintenance section. Whether or not you intended to supply the information to start with I feel what's here is valuable and will be referenced in the future.
