Ford F-150, Clutch Pedal Problems
Q: I noticed the clutch
pedal movement gradually increased to the point where there was less and
less pressure required to engage. I checked the fluid in my '94 F150 4x4
and noticed it seemed slightly down. The Owner's Manual says to add fluid
to the "step" (whatever the step is)?? After adding fluid I
noticed the fluid was contaminated but regained clutch usage. Any ideas
why it would become contaminated or what repairs may be in store for me
in the near future?
A: The
fluid used in most hydraulic clutch assembles is brake fluid. Brake fluid,
by design, absorbs moisture. Because of this ability, the fluid will darken
as it becomes contaminated with moisture. Ideally, the fluid should be
replaced, system flushed, every two years or so. As for future repairs,
"where did the fluid go"? It's possible that the clutch master
or clutch slave cylinder have a small leak, allowing the fluid level to
drop. Have your technician inspect the clutch master and slave cylinder
for any signs of leakage and replaced as needed.
