1995 Chevy S-10 clutch slave

Before you unbolt slave from the bell housing break the hydraulic line loose note: use a line wrench. Once removed unscrew the slave from the line. Reverse this step on replacement then bolt on and tighten line.
Now the hard part bleeding, If you can get a hand vaccum pump for brake bleeding this would by great.If you do attach to bleeder and pump out air operate clutch pedal and repeat till you have a good pedal.
If no pump it gets a little difficult ,so you get a plastic tube, clear is best attach to bleeder place tube in container of brake fluid hold lower than the slave and have someone pump clutch pedal. When air bubbles stop then close bleeder pump the pedal hold down and open bleeder do this till all air is out and pedal is good.
Note: if the master is as old as the slave you might want to replace also. On some models the are sold as a set.
Good Luck
