So I replaced the clutch plate, pressure plate and throw out bearing today, but when I was moving the slave cylinder out of the ways he tip came off and some clutch fluid (brake fluid) came out. I replaced the tip and all seemed fine. After reinstalling everything, I wanted to see if everything worked as hoped, and there was basically no pressure behind the clutch pedal. I had some brake fluid that I was going to use to fill up the master cylinder reservoir, but I couldn't seem to figure out how to open the reservoir to put more fluid in. Is there a special trick? Is there a way for me to refill and bleed the system? Thanks for any help.
