Please see odi#10278394. Complaint continued. Truck taken to garage to be fixed in January 09 because of vibration in steering from brakes. Oct, guarantee run out, and brakes still not fixed. Vibration continued. Ordered new performance rotors and pads. Upon installation of these items I inspected calipers and found cracks and chips in cylinder plungers which connect to push the pads. I would say this came from constant vibration of the front brakes which Ford did not fix for eight months. The center plunger of these caliper pistons are made of a fiber board which will not stand up to vibration, fiber board is a very hard and brittle material which is good for heat and wear but not vibration. Calibers have to be replaced. Of course at my expense. Truck is undriveable and this condition can cause a very serious accident and death if breakdown of this fiber board type material should fail without notice. You would completely lose your control and brakes.
