Nissan Repair: clutch, hydraulic clutch, slave cylinder

Question
I have a 1986 D21 pickup. Recently I noticed that after the truck had not been driven for a while it seemed that I was losing pedal stroke (pushed nearly to floor to release). Discovered a leaky master cylinder and replaced it. After bleeding the system I still have very little stroke to work with. I'm not experiencing any slippage that I can tell and adjusting the pedal free play does nothing. I can't afford to replace parts that may not be the problem and I'm new to owning a vehicle with a hydraulic clutch. Any ideas?

Bernie,

Replace the slave cylinder at the bottom and bleed the system with Ford High Performance Brake Fluid and you should be fine.  The procedure for bleeding should be that someone pushes the pedal to the floor and you crack open the bleeder screw at the slave cylinder and you shut it quickly.  Then the person in the truck lifts the pedal to the top and preses the pedal to the floor again.  Repeat the bleeding procedure until all air is purged from the system.  It is a good idea to have a small rubber hose on the end of the bleeder and the other end in a container to prevent air from back feeding into the slave cylinder.  Also, it keeps the mess to a minimum.
