Mine aren't there a complete different weave. Mine have many gouges out of them, pretty deep aswell and there still going strong. I put a light cover of superglue over just to help a wee bit. But I seriously doubt running bars at different angles will make them snap faster, I reckon there has been a bad batch of Try all carbons lately.
The caliper splits in 2 so it's easier to service. There is a little hole which connects the two halves of the caliper together, with a little o-ring to seal it. If you genuinely still think you are right, I'll try find one at work tomorrow, strip it and get pictures for you.
