Yeah, thats just you depleting the vacuum assist. you should acutally do that before you start bleeding, that way you get a feel for what your brake pedal feels like with no assist, and what it should feel like when your done.(it will probably be even firmer when youre done, firmer is better)

 

By all means good stuff. I have a feeling there isn't going to be much clean fluid in this puppy, the dirty fluid is black. It's at 38,000 mi and I bet this is the original fluid. This is used in the clutch too right?

 

What does that have to do with anything? Like I said before all I could find is synthetic brake fluids in all of the parts stores, not conventional like I thought I needed. After looking further, it seems that most all brake fluids sold are synthetics, just like I'd guess that Delco Supreme 11 is probably a syntehtic. Valvoline claims that their synthetic can be mixed, so all is good there and that's what I'll use
