13 mpg... Maybe a clue? 120-130

Well, after gasing up today, 10 gallons with 135 miles. Man that's bad, about half of what it really should be... Leaning the carbs out results in very poor running, so I'm not sure what is happening anymore.

Well, I did have a new clue Saturday. After going out for a run to pickup a couple tools and some new auto fluids, I went at replacing both of my upper ball-joints.

When I went to remove my hubcaps, I noted that they were very warm. It was sunny and I figured it was just reflective heat, until I got deeper...

My wheels and my lugnuts were also very warm. So warm, in fact, I could not hold all five lugs in my hand. The wheel hubs were also very warm/hot - as were my front calipers. The outer part of the calipers are actually a tad discolored - kinda silvery.

One of my pads is a bit thin, but aside from the heat and the discoloration, I've had no other indication that my brakes are binding. I can spin the wheels freely with no issues.

I'm thinking maybe that my brake hoses are not releasing the pressure when I let off the pedal. I've read that they can collapse internally and function fine to stop, but not allow the pressure to release... I suspect that this might be the problem.

What other symptoms should I be looking for to confirm this diagnosis - you know aside from just replacing the expensive hoses for preventive maintenance?
