RG You'll like this. Bought a brand spankin' new 01 Chev 1 ton dually, first truck I owned with rear disk brakes, a selling feature, at that time I was hauling some heavy trailers. I'd put a lot of miles with drum rear brake pick ups. At 20K miles!! the rear disk brakes were completely shot, had to put on new pads and rotors the Wisconsin salt had eaten away the Chinese cast iron rotors, huge chunks were breaking away. That destroyed the pads. Another note for RG I believe you are expressing a misconception that may be dangerous to your health. Yes as the rate of speed reduction you wish to achieve goes up front brake pressure goes up and for a while, so will rear brake pressure, THEN as front brake pressure increases the brake force loads the front tire and unloads the rear, now the rear pressure applied must decrease or the rear tire will skid.
The highest possible stopping force occurs just before the rear tire achieves zero down force. As the rear continues to raise into the air, the front force applied must decrease or the bike and rider will rotate until a undesirable rider side down condition occurs. This shift in braking force is not so strong in cars or long low slung cruiser motorcycles as they tend to have a much lower CG. With cars the front tires will skid before the car rotates forward lifting the rear tires.
Late model race and sport bikes are beginning to incorporate rotation and loading sensors into throttle and brake controls limiting excessive rotation fore or aft. Us old farts on old bikes will just have to continue to practice our braking control. I have ridden several ABS bikes and done full clamp stops. Trust me ABS can REALLY stop a bike. You must be prepared to absorb the force of your body's continued forward motion with powerful arm and hand control. Add a passenger's weight shift and the limiting factor to a stop may well be your arm strength! This is not trivial; if a passenger does not expect a sudden stop their body will begin accelerating toward the rider through a foot or more of distance, before they strike the riders back with considerable force, not to mention a solid helmet to helmet smack. I did a practice two up hard stop but my wife did not understand I was doing so. A HAND to helmet smack followed a bit later!

From a survival point of view everything is your fault...
