+1 +1 +1.
Hayes Nine's will have a tendency to stuff up. The pistons especially will be the main problem. Heck we were selling a Trek 6700 last Saturday with Hayes Nine XC and it had never been used and already the left piston on the front brake wasn't moving!
When they are adjusted probalby they are fine, but they dont stay that for long.
chmteck - Check to see when you squeeze the lever that both pistons 'push out'. If you see the
rotor being pushed to one side then you probalby have a 'stuck' piston. You will need to 'un-stick' it, by either holding the other piston down and pumping the lever
carefully or lubing the piston. However i suggest you just take it to you LBS if you try the 'business card + re-centering' technique dosn't work.
