A friend gave me his Avid BBDB disk brake and disk, but the pads were far to worn down, so stupid me i tried to replace them. Now, having always run V brakes up until now i have no idea how a disk break works and well im not quite sure if I've broken it, if its fixable or if i should just scrap the disk brake and stay with V brakes... :$ Its sort of looking like this at the moment... maybe i should take it to a bike shop and let them have a look at it... help me please!
