They may be.... Mine was only 1 month old before it happened. The other one was older and not mine. As I have yet to see such a picture of an 810 caliper, I think that those are stronger.
Just get a Trialzone with Hope Tech 3 lever and Jitsie pads. These will be the same or even better (as some members on here say). I went back to Racing Line rim brake on the rear for now.
