I have a 2003 Silverado 1500, 98k miles. The front brakes are either not releasing or building pressure themselves. After driving about 10 miles the front brakes are on without me touching the pedal. They get hot and start smoking if I continue to drive. I have replacesd all calipers, pads, rotors and all rubber brake hoses. The problem is still there. Can anyone help me solve this problem before I replace anymore parts. Thanks.
