Mysterious Brake Parts from Tmec 200

[vet_stingray]

So I have tried to fit some of the cheap calipers and have tried to fit most of the generic brake kits off of amazon and one from ebay with no luck. Does anyone recognize the brake parts and any machine they may also fit on? te caliper looks very similar to the Nissin brakes on my klx, but I have even tried a random Honda caliper to see it it would fit. I am open to suggestions just really want to get my rear brakes working again.
I did call a place here in GA and can buy the whole rear brake set up for over 200 bucks, but was hoping to find a online source, or find out who manufactured these brake parts incase I run into this problem again.
