Why won't my rear calipers always release??

I posted this in the drivetrain problem section but have gotten no response and figure there's more traffic here.

My rear calipers will intermittanly not realease getting the wheels really hot. 130k on the truck and it is pretty much relagated to once a month weekend duty. Could the pistons in the calipers be corroded or do you maybe think it's the rubber hoses going to the calipers? I had one of those hoses collapse interanlly on my 68 vette. Applying foot pressure overpowered the collapse but the pressure of the pistons returning home were no match. I find it hard to believe that both my hoses are having issues being an 05. I would tend to think it's a contaminated fluid issue causing corrosion in both calipers.

Any advice??

Not sure if this has anything to do with it, but on a 1,500 mile trip my abs light came on for about 250 miles. Hasn't been on since. It seems that light came on once or twice last winter also

My truck had the same problem as well. when they sit for while the rails that the calipers slide on get sticky. i only drive my truck on the weekends as well so every few months ill pull the rear wheels off and lube the rails with never seize.

The calipers are known for freezing up if you dont drive it regularly.

I replaced both rears on mine and the hoses last year

Corrosion is an issue too if you don't change your brake fluid regularly. I do mine once a year but it should be done every 2 at a minimum. Brake fluid sucks up moisture like a magnet and then things start corroding.

Thanks guys. I'll throw a new set of calipers on her and flush the brake fluid.
