Abstract: A bow with modified braking uses flexible bow limbs attached above and below a bow handle. The bow limbs have wheels that guide a bow string and form pulleys. The pulleys mechanically assist in holding the bow limbs when the bow string is drawn.

The remotely controlled brake has spring held brake contactors capable of elastic extension and retraction in the directions of bow wheel rotation that engage with a braking surface located on the bow wheel. The modified brake requires an archer to hold some of the pressure of a drawn bow string to prevent the bow wheel from extending the brake contactors which would release the bow string.
