To bleed it, you need the following.
Approved fluid for the clutch master cylinder reservoir.
10mm or 12mm box end wrench.
A buddy to help you.
Bottle or drip pan to catch fluid you'll bleed out.
With the vehicle off, remove the cap to the clutch master cylinder reservoir and make sure the level is at or slightly above the max fill line.
Find the slave cylinder bleeder screw and loosen it a little bit.
Have your friend push the clutch pedal to and watch to see if any fluid is coming out.
If it is, skip the next few posts and go down to the * mark.
If not, loosen the screw a little more and have your friend push the clutch pedal again.
Again, look for fluid coming out.
Repeat till you get fluid coming out. Be sure to keep an eye on the reservoir as well and add fluid if needed.
*Once you have fluid, tighten the bleeder screw and check the level of the master cylinder.
If full, have your friend pump the clutch 3-5 times, holding the clutch pedal to the floor on the final push.
Loosen the bleeder screw till fluid comes out and let it drain for no more than 2 seconds, and tighten the screw.
Repeat this step till you see no more air bubbles in the fluid.
Make sure your reservoir level is full, replace the cap and make sure that your bleeder screw is tight and your clutch pedal should be good to go.How do you bleed the clutch for a 1993 Nissan Truck 2X4 r cylinder?keep pumping the clutch with your hand for a long time, make sure the master is full, if its not working, lift the front of the truck at a 45 degree angle to get the air bubble out of the line that should do it, i hope that helps good luck
