Check that the pedal has the proper free play by pushing down on it with your thumb. There should be 1/16" to 1/8" of easy movement until a firm resistance is felt. If not there is a threaded clevis on the end of thee master push rod that can be adjusted. This 'play' assures that the master fully returns to rest and releases the pressure on the slave. Too much play and the slave does not give a full stroke to release the clutch.


Before putting the hard line on the master, fill with fluid, hold some rags over the outlet and pump the clutch pedal to expel any air in the master and get the fluid flowing. Connect the hard line and slave. Loosen the bleeder on the slave, press the pedal down and hold, tighten the bleeder, raise the pedal. Loosen bleeder, depress the pedal and hold, tighten bleeder and repeat till only clear bubble free fluid comes out. Make sure the master reservoir does not pump dry. Once bled the slave should move about 1.18". The slave push rod is also threaded with a lock nut at the clutch arm end and should be adjusted for a clearance of 1/16" between push rod and clutch arm.
