2002 Dodge Dakota 3.9 the Clutch wasn’t disengaging the transmission. we replaced the master and slave cylinder, the new slave cylinder has a bleed screw i have tried pumping the pedal, normal bleeding procedure, pressure bleeding ran almost 1/2 a gallon of brake fluid through and it still don’t work. the pedal is somewhat resistant when depressed but not enough to disengage the transmission. what shall i do I am running out of ideas, the only thing i can think of is to remove the the master and slave as an assembly and somehow bench bleed.
What tricks do you guys know?
Thanks in advance!

After 18 hours i finally got it!!!!! I removed the Brake Master Cylinder & Brake Booster (to gain access). After that I was able to remove the Clutch Master Cylinder from the fire wall, then I positioned it so it was level. I hooked up a Pressure Bleeder and opened the bleeder on the Slave Cylinder. While the bleeder was opened i moved the Master Cylinder in different positions (level,up, down) I even rapped on it with my screw driver at the same. So after all this I’m going to contact the manufacturer (Duralast) and tell them their instructions are useless! For anyone else reading this get the one piece assembly that is pre bled, may cost more but will save hours of agony and pain.
PS Thanks Collegeman for the article.

Your most welcome. 🙂
Air bubbles rise, so you always have to bleed the highest point last. That why calipers, if you install them correctly, have the bleed screw on top. On a clutch, you have to bleed the master cylinder last. You can get away with not doing this on brake master cylinders if you bench bleed the cylinder first, then any small bubbles that bubble up from the piping will get blown down when you press on the brake pedal to bleed the calipers. This only works because the master cylinder has a large reservoir and it can pump a lot of fluid, enough to sweep the bubbles out the far end.
