The truck is a 1999 Dodge 5.9 diesel 2500 FWD with 4 wheel ABS To date I have changed out the brake pads three times Calipers twice and Hydro boost and master cylinder once.
Had a brake diagnostic and inspection by the dodge DLR. At that time they changed out the proportioning valve to bring the individual wheel pressure into spec. Problem not resolved.
If I let the truck set for two are three hours the right front wheel will turn free and the left wheel will have a fair amount drag.
Could use some help on this one

Do you

I TAKE IT THAT YOUR PROBLEM IS THAT THE CALIPER(S) AIN'T RELEASING

IF YOU OPEN THE BLEEDERS SCREW. DOES IT RELEASE?

IF SO THIS MAY BE A BRAKE HOSE ISSUE

FLUID CAN PASS THRU. BUT NOT BACK-UP.A OLD HOSE SOMETIMES ACTS "LIKE A CHECK VALVE" WHEN IT DETERIORATES INSIDE. LETTING THE CALIPERS "FA-DANGLE" BY THE HOSES, OR HAVING TWISTS IN THEM DON'T HELP OUT THE SITUATION

KEEP US INFORMED

I have spent a considerable time going over the system again to find what I believe the problem. The DLR. Tells me that the brakes are releasing. A closer examination of the calipers indicates the calipers are not free to slide back and forth as they should. Now we get down to it, seems like an easy fix. I removed the caliper bolts and apply silicone grease insert the mounting bolts in the rubber sleeve. They now slide in and out of the rubber sleeve. When I come back about 20 minutes later to install the pads and mount the caliper I check the mounting bolts in the sleeve for their ease of operation and find there are extremely hard to move, the longer they set the harder they are to force out of the rubber seal.
I have used two kinds of silicone grease, Mobile 1 grease, spray silicone. And graft power.
I perched a new set of rubber sleeves from AutoZone all ending up with the exact same results. After about 20 minutes the rubber bushing forms a death grip on the mounting bolt to prevent any slid action to the caliper.

Is there any rust or build up on the caliper slides? Also, is the piston releasing properly? You could, as CJ mentioned, have a bad rubber brake hose.
