yep thats right, take the line off the master. put your finger over the hole. fill the reservoir with fluid, then get some one to pump the pedal and use your finger as if you were bleeding brakes, so push down pedal and release your finger at the same time, then put your finger back on and they lift the pedal, do this until pedal feel is ok then quickly put the line back on and bleed the clutch slave (on the gearbox) with the same process. make sure you dont let the fluid get below the low line on the reservoir
