80mph is too fast. You're supposed to go from 60mph to 10mph, 8 times in a row. Not 80mph!

The energy you put into your brakes goes up with the square of the velocity. So you're not putting 33% more energy into your brakes when you stop from 80 instead of 60. You're putting 75% more heat into the brakes. It's likely that you overcooked your new pads.

See: Instructions for bedding in your brakes and pay particular attention to the 4th paragraph:

Read and understand these instructions completely before starting. If you have any questions, give us a call or email. Do not substitute higher speeds for the 60mph called for in these instructions. The heat in your brakes goes up exponentially as you increase the speed from which you brake. If you make repeated stops from 80 or 90mph with street pads, you will overheat the brakes and may end up having to replace pads and/or rotors.
