When brakes get really hot, the pad material starts to turn directly into gas and causes the pads to "float."

This is not true. Brake fade is caused by the hydraulic fluid boiling, thereby turning an incompressible fluid into a compressible one, thereby greatly reducing the amount of force applied to the pads.

Yes, the GP is true. This is why in sport and high performance applications you often find cross-drilled brake rotors. While the holes do provide some additional surface area to the rotor which promotes cooling, their primary purpose is to give the gas somewhere to go & thereby allow greater pad-to-rotor friction.

That's not to say that brake fluid doesn't boil, however boiling brake fluid is usually caused by the demand for braking force exceeding the components' ability to dissipate heat away from the caliper, or excessive moisture being present in the brake fluid.

Hmm, I'm going to be extremely pedantic and point out that although the tongue is typically considered a "taste organ", they're not using the sense of taste. The tongue is just as much a part of your sense of touch as any other part of your body (well, most any part...), and that's the sense which is being utilized in this case.

You could save the online bills to your computer. Many of them are available as PDFs. But, yes, it requires a certain discipline on your part rather than just having them show up in the mail.

I also agree with other posters that companies don't generally do this to go "green", but to make a buck. That is why T-Mobile's plan sounds more offensive.

Well there's always this option: There's overwise alot of very unhealthy kids and we want to show them that by keeping up a certain heart rate during excercise and eating properly, you can become healthy instead of the useless fatass you currently are.
