Bill,
    Who is this guy?  Have him read the cap on the master
cyl.  DOT 4 only.  Dot 3 is not high enough temp. rating.
 Unless your going to work on your Vanagon yourself
PGh. is a bad place to have a vanagon worked on.  No
mechanics of any value for your vanagon here in Pgh.
                                                   ERic
                                                   Pgh. PA
