I would recommend replacing the rotor on both sides and also replacing your
pads.  This way you have even braking on both sides and a fresh start for
your front brakes.  Changing these items is actually quite simple especially
for the syncro as the rotor is removable without taking off the hub (all 2wd
Vanagons require this and fooling with wheel bearings, where you do not have
to worry about this.)
I have new, VW brake pad sets for $25 (does both sides) and front syncro
rotors for $50 each (German).  Give me a call or order through the web store.

Thanks,
