Air in the master

[kenwheeler]

After the weekend clutch work I put my son in charge of bleeding it while I went to work. He called later to say that after pumping and pumping, he couldn't get any pedal. Opps, forgot to tell him you don't bleed them like brakes. I'm guessing air in the master, is that correct? To fix it, I disconnect the line from the slave, unbolt the master, position the master pump side up rod side down and the evil bubbles should escape out the resevoir, is that correct? If I push on the rod with master in this position, should I be able to feel strong resistance after the air goes away? Or should I just replace the master so everthing from pilot bearing back is new? It's a 94 Ext cab 4x4 with a 3.0 and it's hogging up garage space that could be used to replace the 2.9 in my 87 zebra ranger. Thanks

No need to replace the master.

Just tilt it up and pump the rod like you said. The master is positioned in such a way that air gets trapped in the top portion.

You need the slave connected though.....if you disconnect the slave and then attempt to pump the rod, you'll be in for a challenge. It wont move at all. (unless you have a leak or something)

With the master tilted, pump it a few times and hold it in. Have someone open and close the bleeder on the slave and then let the rod out. I can't imagine it taking more than 2 or 3 cycles to get all the air out.

^ good advice. And a pretty easy fix!
