I know if I had time to lift the car one wheel at a time, I could have more info...

But when the weather is warm/hot, brakes act up and bind. Car won't roll back on a hill. The next morning, fine when it is 65F or cooler.

I replaced my two rear calipers earlier this year.

ABS light has been on for a while.

Just find it odd only when it gets warm/hot outside. I first suspected parking brakes, but it doesn't matter--parking brake left off, as soon as the car is driven, it's already sticking, if it's like 80F outside....when the car was parked without the brake and it was cool, was not sticking....any ideas?

edit: maybe not a brake?
