Yes, you put brakefluid in the reservoir it even says on the clutch reservoir cap. Anyways you said it was completely empty? correct? then you filled the empty reservoir and took it for a 30 min drived, dude you gotta go to the clutch slave cylinder and open up the bleeder bolt, than have someone else pump the clutch about 10 times doesnt need to be that number exactly but more than 5 will typically work than on the last pump have them hold the clutch all the way down and then you tighted back up the bleeder bolt nut, now check the reservoir??? if it drank all the fluid you just put in there then re-fill it and do it again, and keep bleeding it till it is completely compressed throughout the entire clutch system and holding the fluid in the clutch reservoir as well and you should be fine. goodluck
