I think you said this but be sure and ONLY use Dot 3. I believe many of the Dot4's are
synthetic. Your seals will fail with
synthetic brake fluid. Once you fill your reservior lay your bleed line down in a jar 1/2 full of fluid and open the bleeder. First allow the fluid to gravity feed out and then submirse it into the jar below the fluid line and then pump your clutch with your hand slowly. Then try and close the bleeder while it is still submerged. Get an assistant to help you by pumping the pedal and holding it down while you crack the bleeder to purge any remaining air (tap on the feed line with a screw driver to dislodge any stuck air bubbles). Takes about three time to get a good firm pedal. My appologies if this is too simple of an explanation.
