General brake question

i don't get my answers from fortune cookies.
You're right. But the reason I'd posted this thread in the first place was because I've read lots of people with similar symptoms, and they just threw money at it, changing all kinds of parts, with no fix. So I was trying to zero in on the next component that may need replacement without wasting too much $$. I've replaced master cylinders in the past which did not fix the brake problem. But in the end everything is ok and everyone's happy.
