Well, I had this same problem and I ended up replacing the starter.   
 Apparently what happens is that the starter motor turns, (thus the hum)   
but the binhex doesn't pull out to engage with the flywheel to turn the   
engine over.  One way to get the Vanagon going is to go under the van and   
while someone turns the key, hit the starter motor with a hammer until it   
engages.  A couple of weeks ago it was 9 degrees in upstate NY and I   
refused to go under the Van to start it.  I have no idea why the starters   
do that but that's how to solve it.
I bought a Bosch reman starter for $160 in my area and paid a mechanic   
for 2 hours work.  The dealer wanted $375 for a reman.

If you get a solution to the break problem, please share because I have   
the same exact problem.
