I bought a zhi v brake adaptor to put it on my echo pure fork, which has magura mounts. So, I put the adaptors on, and was putting one vee arm on, too (shimano deore), but when I tried to put the pad on, it didn't contact the rim the way it should do it. The half of the pad was off the rim. And I couldn't get it to contact the rim normally. Tried to change the holes of the adaptor, but still the pad didn't fit properly. Is the fault in the adaptors, or where? I don't know how can I Put the pad on that it contacs the whole rim, no only a half of it.
