The disk brakes on my Trek 6500 make a loud squeeling sound whenever I stop. I bought the bike near the end of last season but I don't remember the brakes making a squeeling sound last year.
The brakes work fine and I have no issue with their performance, other than the laoud squeeling sound they make under medium to hard braking conditions.
Other than oiling my front and rear disks ( ) is there anything I can do to fix this problem? Its more of a nuisance, but it does distract from the ride.
