ok I've read this post and a vehicle that has sat for a while will have sticky brakes/cailbers. It could have moisture in the brake fluid. But having had this problem with more than my fair share, I've found out if your brakes are heating up it's most likely due to bad brake hoses.The brake hose is made of a double wall. otherwise a hose within the hose.
What happens is the inner wall delaminates from outer and collapses. When you apply the brakes you force brake fluid thru the collapsed hose and it activates the caliber/wheel cilynder. When you release the brake pedal,the fluid is no longer under pressure and it relaxes the caliber/ wheel cilynder. When the hose is defective the fluid that's between the hose and caliber/cilynder gets trap by the collapse hose and keeps pressure against the caliber. After a short period of time the fluid that is trap will bleed back thru the bad hose and the brake relaxes and frees up. A quick way to see if this is the problem is apply the brakes firmly with the brake/ wheel in question jacked up in the air, and try to spin the wheel, it will be locked due to the fluid,... take a wrench and loosen the bleeder valve just a crack, the fluid will spit out and your wheel should spin free, if the wheel is still stuck then you know its a caliber and not a hose . I understand that you passed on this B, but this is a common issue with any vehicle that has hydraulic brakes
