if it "eats brake pads",then either the pads are too soft,the rotor is
warped or too grooved,your caliper pins and guides are not free and
lubricated(sticking caliper),OR ***you ride your brakes***.
does a pad on one side of a caliper wear a lot more than the other side?
that's a sticking caliper. If the wear is even on both sides,then you're
likely applying the brakes too much.
I see a LOT of people driving and their brake lights are going off and on
while they are NOT actually slowing down for anything;they are probably
left-foot braking,and their foot is unconsciously riding the pedal.
(If your reflexes are that bad that you need left-foot braking,then you
should surrender your license.)
Drive the proper way and right-foot brake,as you would for a stick-shift
transmission. You will also avoid "unintended acceleration" incidents.

Did you replace the "entire caliper" with a rebuilt one or one from
a junk yard?
Another thought, was this auto ever involved in a wreck, perhaps
from that particular quadrant?

Do you know that it sticks? Or are you deducing this from the
uneven wear? Does that wheel drag more when you spin it with the
front jacked up?
Could there be residual pressure in the hydraulics because of
another problem? Due to road camber or wheel alignment, this
just might show itself as wear at the kerb-side disc.
What about excessive play in the RH front wheel bearing.
