It sounds more like there is a problem with the clutch hydraulics - either
air in the hydraulic line or a bad piston/seal in the master or slave
cylinder. Check both cylinders for leakage around the open end, and bleed
the clutch with the screw adjuster set to a reasonable point.
There should be a small amount of free play in the mechanical parts of the
linkage, both at the release lever and at the pedal. Then, when you press on
the pedal, the resistance should build within about 1 inch of the top of the
pedal, and should remain relatively constant all the way to the floor. The
clutch should release pretty quickly after the foot resistance starts to
build. If there is no free play in the linkage (and the clutch piston rod
can't be shortened enough to give you free play) then the clutch disk is
worn out and needs to be replaced; conversely, if the pedal resistance
doesn't start until a couple or three inches down then either the mechanical
parts have way too much play and/or there is a hydraulic problem. Normally
the slave piston will take up a position such that there only is a very
small amount of free play - so if that appears to be OK but the clutch still
doesn't release until the pedal is very near the floor, then something
strange is going on - potentially a warped clutch disk or galled pilot
bearing.
Good luck,
Theo
