hey all - i was recently out on a ride, going down a fairly short but fairly steep decline, when i realiazed that my front brake was not cutting it. i almost went into the stream on the other side, but managed to sort of slide sideways and get a foot down. i cannot back pedal that strongly due to flat pedals, and i really want to keep the flat pedals on... would a disk brake help me out here, or am i asking to somersault? i am riding a fixed with a front brake only. i was thinking avid mechanical or whatever is cheap i guess... thanks for the help - i don't know brakes at all.

ps. i use a shimano 105 brake now with a cheapo bmx lever...
