Weekend before last, I replaced the clutch master and slave cylinders in my
B. There had been a lot of discussion on the list just before this about
how hard it is to bleed a clutch and I didn't remember it being that bad,
but my last experience was 15 years ago.
Years ago, I owned a '79 Spitfire and when I replaced the master cylinder,
I let the car sit for half a day and then pumped the pedal a couple of times
and the clutch was bled, but the clutch line in a Spit is strictly vertical.
After the new cylinders were in the B, I bled the clutch at the slave cylinder
with my boyfriend working the pedal. This obviously wasn't doing any good.
Then we bled at the connection to the master cylinder. This actually caused
the actuating rod down at the clutch to move and the clutch could then be
pumped up so that the car could be shifted, but at a certain point, it became
obvious that no amount of bleeding at this location was going to get all the
air out of the system. I was out of clutch bleeding time and I had to drive
the car to work, so I drove it pumping furiously on the clutch pedal every
time I needed to shift. After three days of this, the clutch no longer
needed to be pumped up--it had bled itself. I'm not sure if I'm recommending
this as a procedure to be followed because pumping up the clutch for every
shift is tricky. I'm a trained professional and can do this while eating a
carne asada burrito.
Someone (Motorhead?) suggested pushing the slave cylinder rod into the slave
cylinder after the system had been bled as much as possible. Based on the
geometry of the system, this should work, but I don't know how difficult this
is because I've never done it. If I were going to do it, I'd use a big pair
of water pump pliers to push the end of the rod into the slave cylinder
housing with the cap off of the master cylinder.
Good luck!
