Cracked Brake Pads, any others? Options

[exxtractor]

I had Toyota brake pads installed last year, and Toyota brake rotors machined. However, on Monday during maintenace service I was taken to the garage and shown that I had cracks in left brake pads (didn't see the right ones). This is the second time this has happened, and the Toyota guys belive its my driving style, which I would say is heavy on the braking when coming to a stop, I never ride the brakes, or drag from light to light. I'm guessing heat related? Also I have a worn wheel bearing on the left side, and needs replacement along with a hub and seal. Anyone belive this might be an issue with the cracked pads? Also any suggestions for high quality brake pads?
