I replaced the brake drums on my '87 Westy. I loosened the brakes up to get
the new drums on.  I figured applying the brakes would cause them to
self-adjust. The pedal now goes almost to the floor when I apply the
brakes. The brakes are working, as I jacked the van up and checked.  I
tried to get the new drums off, but they were pretty well stuck on.  Any
thoughts?  Could the self-adjustment screws be on the verge of ratcheting?
