Got the truck back after 4 full week at the dealer. They say the brakes were cleaned several times and the brakes tested several times including the service manager trying to turn the wheel with brakes applied, while up on the lift. (I had to laugh at this test). They covered everything under warranty, including the 4 full days of a rental car.
I tested the truck brakes on a gravel road this weekend and found that the service brakes will now lock up, but the e-brake will not. I'll check it again in the future to see if oil starts seeping out of the pads.
Makes no sense that FCA will pay for all that labor and rental car ($140) when doing it the correct way would be an hour of labor and maybe $30 (their cost) for new pads.
Will likely replace the pads myself in the near future and not worry much about the e-brake.
