Two quick questions on a clutch master / slave cylinder replacement on my rusty Protege. I also picked up a hydraulic line because all of the parts were so cheap at rock auto. I haven't done a job like this, and I noticed that the clutch is using the brake reservoir for fluid. Maybe this is a silly question, but how do I make sure I don't drain my fluid while replacing the two? I really don't feel like bleeding my brakes all over again. I did a bunch of searching, and read some people are also having problems finding the interior master cylinder bolt. Can anyone point me in the right direction for that, too? Thanks!
