Thank you for the information, Bob, I appreciate it! I imagine you are right about inspecting the master cylinder. I traced all the brake lines, and they look good with no rust pitting or wear from rubbing on anything. We live in a dry climate, so that helps keep external rust away for the most part. I looked it up, and a rebuilt Hydro-Vac from Napa is $288, but since mine seems good so far, I think I'll leave it, although I do agree with you a braking system is nothing to skimp on.
So far the brake fluid I've removed from the system has been somewhat dirty...I guess a system flush is in order?
How do I tell if I have the Huck design?
Thanks!
