I've got a 2000 B3000 and the clutch play keeps changing. Some days I
get in and it's hard and works perfectly but sometimes I get in and
it's to the floor before I can shift gears and I have to drive around
using 2nd and 4th!

The fluid levels are fine when I check and if I bleed the clutch the
pedal firms up for a few days but then goes back to being hard and
soft at different times.

Any ideas?

Thanks in advance

I think you possibly have some problems with binding pivot points. Is
the slave cylinder internal to the bell housing or external. I have
seen the internal ones wear and the release bearing binds on the
surface in should slide freely on. Cylinder replacement is the only
lasting repair. If the cylinder is external with the release bearing
internal, I have seen the pivot on the release fork get worn and the
input bearing collar on the transmission get very sticke from clutch
dust and road dust. Clean and lube these points with a graphite lube
so they don't attract dust again.

And that's related to too much free play between the slave
cylinder piston and its lever. If the lever or release bearing is
sticky, it will travel just far enough to let the clutch grab.
Vibration from the engine or road can cause it to release further,
especially if there's an external retraction spring, and the excessive
free play now means a whole bunch of pedal travel and incomplete
disengagement.
Maybe that external spring is missing. Clean the pivot and
release bearing slide, install a spring if hthere's supposed to be
one, and adjust the free play to specs.

Dan Thomas probably more of a mechanic than we are:
However other suggestions, cos our symptoms were very similar.
A leak? Somewhere.
Or a defective (by-passing) master or slave clutch cylinder.
Ours recently was a defective slave cylinder (the one that operates
the clutch) on a 95 Nissan.
It was also leaking slightly! We happened to have a new spare on hand;
we must have seen the problem a couple of years ago and got the slave
cylinder in anticipation!
Good luck.

Air is getting into the system. Your job is to find out where. The
master cylinder is the most popular place, but it could be the slave or
a hose.
