I was at the local shop that sells used components from bins "as is". I noticed there are Vanquer 600/999 red label brakes and 600/999 black label brakes. Any difference. Also, there were some brakes stamped Vanquer 999, but looked a bit older and maybe not as good of quality. Anybody know of the time period for that last one and what bikes it came on? Any significant difference in any of them as far as prestige? Thanks!
