I would second tom's observation. Happend to me twice. The 2nd
time was also right after replacing rotors and rebuilt caliper.

What I ended up doing was to adjust the rear pads further away so when
you spin the wheel in the air while adjusting the caliper under car,
you should hear no more than tiny little bit of rotor/pad contact over
one revolution. 

step on the brake couple of times then re-check the clearance by
spining the wheel. Once satisfied, tighten up handbrake adjustment but
make sure it does not apply not even slighly pressure to the levers.

The adjustments seem to differe slightly from car to car. Ie .004 in
may be loose one one car but too tight on the other... 

I use Rich Hirsch's article from i Saluti, Nov 1993 almost exclusively
for adjusting rear brake.
