I have an '84 Bronco II with a toyo kyogo 4-speed that won't shift into gear. The clutch hydraulic line was empty. I check it once a month so it happened suddenly. I tried to refill the line so I could look for a leak but I can't pump the fluid past the master cylinder. I have little experience with automechanics so my questions are:

How do I bleed the clutch line? I didn't find a bleed screw on the slave cylinder.

The hydraulic line is made of a pre-formed, red colored hard plastic. If the line is cracked, do I just replace it with a rubber hydraulic line?

 

You can get a replacement line I believe. You should see obvious signs of leakage with it loosing fluid that quickly. And there is a bleeder on the slave somewhere, or at least there was on the slave in my '85 w/a TK5. Has it been sitting? It may be that the clutch disc is rusted to the input shaft, when you push in the clutch the disc is not floating between the flywheel and the pressure plate. Just a thought, there is a roll pin you drive out to remove the line from the master cylinder, you might try pulling the line out to see if you can make the master pump at all, it could be a clog from running out of fluid. But brace yourself for replacing the slave soon anyway, if you're loosing that much fluid chances are it's leaking out at the slave, meaning it's not long for this world.
