I have a braking problem in my 3500, it's a single wheel 4x4 with 64000 miles, I took it in for a oil change and tire rotation and when I got it back the front end shakes upon braking. It doesn't do it all the time and can go for days without doing it and I suspect something like the ABS system, everyone advises it's a rotor but if that was the case it would do it all the time. If your wondering why I don't just take it back to the dealer during the oil change there was some bad blood over them trying to up sell me with a cabin filter that I questioned why the mechanic was in my cab removing the cabin filter for a oil change, this also created hour longer wait after I was called in saying it was done, I actually think something was sabotaged with the abs and I just haven't found it yet. I have rotated the tires back and looked at the rotors and pads they basically look new as the truck stays in a garage unless pulling equipment and stays in town never braking with a load at highway speed. any Ideas? Any Chevrolet recalls on this anyone knows of?
