Dear Fellow MGB enthusiasts. As you well know, the B clutch can be an absolute bear to bleed. It can be really tough to build up a pedal, especially say; after replacing the flexible hydraulic hose, or Clutch Master Cyl.
This is nothing new, but I wanted to report that the Gunsons ezi-bleed did the trick for me. Its an ostensibly simple system that uses spare tire pressure to force fluid from the reservoir into the lines.
Connect it up & simply drain fluid via a flexible tube into a "baby food jar". When the bubbles stop - tighten the screw back up. I realize that everyone may not have this experience, but if you havne't tried it and are frustrated like I was - it may help!
Kind Regards,
Don
 
Don, good idea and I heard that it works well. For those who do not have this set up here's another way. Push the slave all the way inside and hold it with the bleeder open, while your buddy pumps the pedal and keeps the master full. As soon as you get a steam of fluid coming out, close off the bleeder and it should pump right up, now when you get pressure open up the bleeder a couple of times and that should get rid of the air. This system has served me well for many years, but I have had in the past more trouble getting the master to start pumping, so I always bench bleed a new or rebuilt master now. Wayne
 
I have an EZ Bleed and it works well. But the one major design flaw is that you aren't supposed to use more than 8-12 PSI IIRC. That means you have to let most of the air out of your tire before using the tool, then pump it up again. And even at the recommended PSI, the reservoir expands alarmingly under the pressure!

I plan to cut the valve attachment off and install a quick connect for a compressor air line. Then I only have to turn the regulator down to use the tool.

I bleed the clutch slave by taking it loose from the transmission and holding it in my hand with the bleed screw in the uppermost position. I have someone lightly push the pedal and at the same time I push in on the pushrod to force the fluid from both directions out of the bleed screw. It's a bit of a juggling act, but not too tough. I think that dimounting the slave and holding it so that the bleed screw is up is the key. In it's mounted position, it's not exactly at the top and it's very difficult to get the air to go out the bleed screw. That's how I do it. 100 percent effective and no special tools required.

I love my EeZi- Bleed.

Steve_S: what I did is fit a Schrader valve into a compressor line adaptor. No need to cut the connector off the tool.
