Has anybody had a problem of not getting any fluid out while attempting to bleed the clutch slave cylinder? Here is what I did; I had my partner push the clutch pedal all the way down, then I open the bleeder valve about 90 degree, nothing came out, try again and I opened the valve 180 degrees, no fluid-what did I miss here? what is going on? anybody experience this before? stoped and realize I better ask before I screw things up..
