Came down a big hill, as we arrived at our destination, and as we made the turn, bad burnt rubber smell. I checked all fluids, all ok, and tires ok. I'm thinking brake pads? Anyone experience the same, after braking on a rather large hill. With a heavy rig? F350, carrying a 3670RL. Fully loaded. Plan to take the truck for a ride, before hook up, to check brakes on the truck alone. Thoughts????? Trailer is a 2009, with not that many miles on it. Truck brakes were done not long ago.
