Okay, well I did tear it down and decided that the pins were, if anything, short on lube. But, the pins didn't feel like they were sticking, and no real problem there. Added a little more lube.
We are talking about the front brakes to be clear.
Pulled the rotor completely off and looked at the other side. The hidden side looks normal and is not blued. Am I simply getting obsessed about the bluing indicating a heat problem? It isn't a clump of blue spots, it is a nice smooth band 1 1/4 inches across, all the way around.
This morning, I drove it 15 miles and exited the freeway, downshifted and stopped the last 10 mph with the hand brake. Then very gingerly touched the right and left rotors. Both were just slightly warm. The left side may have been dragging at some time in the past, but it wasn't today.
Added bonus: with all this attention to the car, I realized last night that the water pump is leaking. Imagine my frustration. My problems/costs are seriously multiplying. (New Nissan starter last month, new tires this week too.)
I have 95,400 miles. I changed to Texaco Dex-Cool at 37,000. Have been a big proponent of it. That isn't a terrible pump lifespan, but I will note that recently Nissan has started warning against the use of these OAT coolants, without saying why.
