Al,
First of all, clutch fluid and brake fluid are the same. Second, your
bleeding procedure is correct, as far as you describe it.
I gather you are keeping the reservoir in the master cylinder filled,
and that the stuff that's coming out without bubbles is fluid, not air:>
Which means there's a large pocket of air in the system. There are a few
possibilities.
#1 - is the bleed valve on the top at the slave cylinder, or at the
bottom? It MUST be at the top, or there's no way to get rid of air
trapped up there.
#2 - there's a big air pocket in the line. Perhaps you're just pushing
the pedal too gently to move the air into the slave cylinder, where it
can escape. Slam it to the floor!
#3 - the air pocket is too far from the slave cylinder to reach it in a
single pump, no matter how hard you push. It moves back up to the high
spot as soon as you're done pushing in the pedal. If this is the case,
you'll have to give it a shorter downhill run. Disconnect the slave
cylinder from the bell housing (leave the hydraulics connected). Very
gently raise it until it's the highest point in the system. You're going
to bleed it up there, so consider how you're going to keep fluid from
squirting where you don't want it to go (paint, carpeting, eyes...)
Before you crack open the bleeder, pump the pedal a couple of times.
This will push the slave cylinder piston out against its retaining ring
(caution - I cannot personally guarantee that there is currently a
retaining ring in YOUR slave cylinder. If there isn't, the piston will
fly out. Don't let this happen!) The pedal will suddenly go from real
easy to real hard when the piston hits the reatining ring. Now bleed.
When all the air is out, your pedal will be rock hard. Reattach the
slave to the car (bleeder valve up).
That's it. You're done.
