Hey:
I agree, its hard to explain. When I say "all the way out of the tube", I mean the fluid is not flowing out of the tube. It flows out of the nipple into the tube, and travels about an inch before stopping.

Master cylinder cap is off but not the diaphragm. But I read a lot of forums that stated it was not necessary to open and close between each pump of the lever, so I havent been doing that. I will try that though.

And no john, I haven't investigated filling by the calliper, but I will look into.

Thanks everyone. It might be calliper or MC disassembly time soon. The help is great and Ill keep you posted.

Take the diaphragm off the master cylinder & leave the cap off while you do this. Fluid has to flow freely from the reservoir into the master cylinder area. Unless there's a dust storm in progress during this work there's no good reason to put the cap on and several reasons not to. The diaphragm probably is preventing the master cylinder from refilling on the next stroke.

BTW- the master doesn't move much fluid per stroke. 1 inch of fluid into your tube might be about right.

Hey,
I did it today. Finally. There was just more air that I didnt get out with the earlier 'multi pump' method. What did it was pumping while opening the bleed screw, closing the bleed screw when the lever was fully (or 3/4 depressed) and then releasing. I had to do this twice, the second time after letting the line sit for a while. I was really relieved when it worked. Thanks everyone.

Glad it worked out.
