Loud grinding noise when braking on 2002 Honda CR-V

When I press on the brakes, a loud grinding noise happens. The harder I press on the brake, the louder the sound.

Sounds like your brakes are down to metal to metal and will need to be repaired and you can get this estimate here http://repairpal.com/estimator?car_type_id=3464 and locate a repair shop here http://repairpal.com/directory?address=06810&car_brand_names=Honda
Is the sound from the rear? There is a service bulletin for the calipers
