In 08 I bought new a 2008 model F250 and have 100k miles on it now. The only issue i've ever really had are with the brakes. Over the years I have had multiple issues with brake calipers not fully releasing. This normally happens on the front left but all wheels have done this. To date I'm on my 4th set of rotors for the front and 3rd set on the rear with multiple pad replacements. So back in mid 2015 I had the brake system flush done again and have had no caliper releasing issues since. The only problem is that the front rotors were badly warped from past issues but I was scared to replace them again. So since 6 months had passed with no issues I decided to have my local Ford dealer replace pads and rotors yesterday on the front. Today I took a 20 mile drive and they didn't fully release again causing the normal bad smell and white smoke rolling out from both front fender wells. On the way home I dropped it back off at the Ford dealer so they could see first hand. To date I have used 3 different dealers and spent well over $3000 on brake parts for this truck. Can someone please help me? I'm at a lost and none of the dealers seem to have a clue as to what the issue is. By the way I have used both OEM and Napa brake components. Thanks in advance.
