    They are right. You just need a brake job. How much brake pad material do you have remaining? Stop by Milt's in Vallejo and let Adrian take care of it.

    Definitely needs rotors. Is it a 4x4? If so, does the grinding noise only occur when braking? If not, those had issues with the auto locking hubs making really weird noises intermittently.

    yes the grinding noise is only when i brake,pulsating too.At first i thought that rotors needed to be resurfaced but that isnt the case,had the pads replaced that didnt do it either.Yes it is a 4 X 4 V10..1999 F-350,gas engine..any solutions?

    Did you replace the rotors or resurface them?

    Yes, the hub/bearing assemblies are a possibilty. Did you just do the front brakes? I ask because this vehicle has disc brakes in the rear that can pulsate as well. Not as common as the front, but still a possibilty.

    Check to see if your lower caliper bolts are still in place. They can come loose and fall out. The whole caliper will pivot and rub against the inside of the wheel. Look for a groove on the inside edge of the wheel from the side of truck. Can eat into and cause wheel failure!
