Reply to "How do I determine if the slave or master cylinder is bad?"

I had the same problem with my car, and almost got stranded once. I took out the master and found the spring inside had broke, so it was not drawing back enough. So I had that replaced & all cleaned, and a visual inspection looked all ok inside the master. Then once back in the car, it was even worse (proving that visual inspection does not really work). One thing I did notice when my master was not working was that the break fluid would actually come into the reservoir when pressed. So out came the master again and I finally got a new stock one, and all works great now. Maybe take a look at the plastic reservoir when someone presses the pedal. But don't take the cap off, as mine was shooting out pretty hard (not good for the paint!).

Plus I hope you got all the air out. I used a manual hand pump at the slave which worked geat. Also tighten the slave screw tight and adjust everything correctly.
