How do you bleed the clutch reservoir on a 85 Nissan King Cab Truck 4-cylinder?

Simply loosten the line, pump it one time , tighten it let your foot off of the brake and loosten it again and pump it one time etc until no more air comes out then do the same for the slave cylinder.Sometimes it is hard to get all of the air out but persistance will prevail. DON'T PUMP THE PEDAL as that muxes the air in the fluid.
