The Clink sound is not unusual when you tap on the brakes. There is a slight space between the rotor surface and the brake pad. You are hearing the mating of those surfaces. You must good ears. I hear that only at street speeds, not highway speed.
Try a can of spray brake cleaner. Spray the rotors and get the dust off, let it dry (30-45 seconds) and see if the sound changes.
Now, If you are talking about the gas smell when you start the truck up, the ecu does not do the emissions part awhile the engine is cold. The ECU will add extra gas into the cylinders and it will do a revolution extra so all the cylinders are primed with fuel, so yes at startup it will smell like fuel.
Take off and do a drive. When the engine is warm, then it will do the emissions thing and go lean. You should only smell hot brakes, oil, and whatever is in the ashtray.
