I have a 2011 limited and both brakes on the driver side seem to be dragging. After about thirty minutes of highway driving I can get out of the truck and smell the brakes. The driver rear is the one I smell the most. But they are both extremely hot compared to the passenger side. Any help would be greatly appreciated.

 

First thing I'd do is check the caliper hardware, then thoroughly bleed the brakes.

If that doesn't work, I would likely suspect the rubber hoses or the caliper, or both.

 

Ok thanks I'll give it a go

 

Check the rubber brake hoses. They can collapse, not releasing pressure.
