Hello All.Last week during a trip home i felt a new vibration in the truck.It came on kind've sudden.After stopping,i noticed smoke coming from the right rear wheels.The smell was terrible.I figured it was a stuck caliper.Today,10 days later,i finally removed the right rear wheels to check things out.The caliper appeared to have very minimal brake drag.The slide pins were NOT seized and had adequate lube.Any ideas?If the parking brake system was messing up shouldn't both calipers have stuck?Should i just "throw" a right rear caliper at the truck?
