When I took my Ranger on it's first road trip after it had been sitting for a few years.
I trailered it home, put new tires on it, changed all the fluids, got it inspected, insured etc. One Saturday around the 4th of July, we loaded it to the gills with stuff, my two boys hopped in the back and we headed to my in-laws lake house about 60 miles away. My wife and daughter went in her car. About 40 miles into the trip, it started overheating really bad and losing power. I had lurked on here enough that I knew 2.9 + hot = cracked heads and I was freaking out. I pulled over in the 105 degree heat with no shade in site, popped the hood and waited. It cooled down and I took off again. 5 miles down the road, it started doing it again. I pulled over into a parking lot and both front calipers were frozen (Sound familar BrutusT?). I finally got it cooled down enough where I could get the front wheels off and wrenched around on the brakes enough that I got them free and got to the lakehouse breaking with the parking brake. Anyway, to make a long story short, I ended up replacing the brake lines, calipers, pulling the encrusted radiator off etc while lying in the dirt and trying to avoid fire ants.
Good news - nothing's ever happened since.
