Rear brake pad short life

At 19,000 miles my rear brake pads wore out on my 2007 K1200GT. I was on a trip in northern Canada at the time so a long way from any kind of service. By the time I got home the dealer says the pads, disc, caliper, and brake line have to be replaced. I had the 18,000 mile service done and the check list said the rear pads were fine. Because I rode the bike for too long with worn out pads, the dealer says it is not covered under warranty, the same dealer that did the 18,000 mile service and the bill will be approximately $1,200.
Has anyone else experienced such short rear pad life? I never use the rear brake pedal. Most of my miles are road miles with very little use of the brakes.

Wait, the dealer checked them at 18K and they were "fine" then 1,000 miles later they were worn down past the metal? And by the time you got home, the caliper itself was damaged?

It is possible although very unlikely that a small rock or something got kicked up and lodged by the brake pedal keeping the rear brakes dragging. Otherwise, it sounds like the dealer didn't check them and they simply wore down to the backing plates. But damaging the caliper and brake line too? That would take an awful lot of excess heat . . .

Did your brake pad wear light come on at any point during all of this?

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

Did a "how to" here: Rear brakes.

I can see how this could happen easily as neither my light nor the wear indicators showed wear, but the pad backing material was already starting to hit the rotor. I got lucky:

I'm sure my rear pads won't last long at all since they are pumping brake dust all over the rear rim. It appears to me as though the proportioning valve favors the rear wheel, much more than it did on my RT. As for your dealer situation I agree with Ken, they can't have it both ways. Either they checked and everything was fine, or they lied at the 18K service, and never looked at the brakes. Either way if you pad sensor did'nt work warning you of this BMW should be responsible for everything, but the pads. Call BMWNA what do you have to loose?

x2 on Meese's comments.

Something just don't smell right here. A thousand miles later costs you $1200?

How can you damage a caliper unless the pad's backing plate is gone, much less the hydraulic brake line? You might want to speak with the shop owner. Can't hurt (hopefully).

No way your brakes should have worn out so soon under the conditions you described. I would ask them to take a second look and offer up a better solution. If they can't do better, Ride the bike home and do the work yourself.
