I'm having a hechuva time bleeding my clutch. I recently installed two new master cylinders and a new clutch slave cylinder and against the advice of some decided to use DOT 5. The brakes were bled and work fine but after bleeding the clutch slave cylinder at the bleeder valve with a Mityvac and bleeding the master cylinder with the help of of someone pumping the pedal, I can't seem to get the air out - if that is the problem. Every indication is that there is air in the line since after pumping the pedal a few times the pedal resistance is at a proper height. Could there be another reason? Is there a better technique for bleeding the clutch? If DOT5 works for the brakes, why wouldn't it work for the clutch?
