Listees!

I have just put 500 miles on a 81 vanagon westy rebuild.  Prior to this the
van had not been on the road in 7 years.  The brakes are all new basically,
new shoes, rotors turned, new wheel cylinders, etc.  I've noticed lately
that when I travel at slow speeds, I will get this intermitent
chirping/clicking sound which  sounds like it is coming from both sides of
the vehicle.  I can touch my brakes (while rolling)and the sound normally
disappears.  It does seem to be worse when I am cornering.  Is this anything
should worry about?....Im taking it for its maiden voyage next weekend and
am a little nervous about these sounds.
Any advice will be appreciated.....Oh BTW, the wheel bearings have been
repacked.

Thanks
Scott
