(1) I was in heavy stop and go traffic, keeping with the flow of the traffic. At one point I had to slam on my brakes. The truck felt like it didn't want to stop. The brakes felt "greasy" and I had to avoid rear ending the car in front of me. (2) brake failure due to overheating? rotors were warped after that. Truck shuddered when applying the brake. (3) a Ford dealer turned the rotors at 25,632 miles. At around 28,000 the shuddering has returned during braking. Dealership says it will not fix the problem again under warranty.
