I bled the brakes a couple of weeks ago (on my 2000 2.0L Focus) Zetec and
with it the clutch hydraulic fluid as it's all part of the same system.
Since bleeding the clutch fluid, when I depress the clutch pedal all the way
down, there is a distinct "rubbing" sound. If I lift the pedal an inch, the
noise goes away and the clutch is still sufficiently released to use as
normal. The noise definately wasn't there beforehand.
