I don't think this is disc warping, that tends to show itself as vibration through the brake lever.
Sounds like one of your discs has become 'dished' - this tends to happen when the pistons in one side of the brake caliper stick in the bore and fail to extend properly when the brake is applied. The extra push from the pistons on the working side force the pad against only one side of the disc causing it to dish inwards or outwards.
Check to see if your pads are wearing evenly - that's another tell-tale sign.
I had this happen on the VFR a few years back. It became so bad, the edge of the disc started to eat into the inside of the fork stanchion. Had to buy new discs.
EDIT: sorry, just noticed they were fitted to another bike so you will not be able to check pad wear.
