I have the same brakes on my 85.  When I had brake work done on the front they did not replace the dampening shims.  I had loud squealing brakes.  Ken Wilford, from Vanagain.com  sold me a replacement set and I installed them.  the brakes are now quiet again.

this is why I have a garage that works on vanagon’s only 10 minutes from my house and I refuse to go there.
