I have a 2009 Dodge Grand Caravan that the brakes are getting hot on only when I pull a hill. They cool coming back off the hill. I started off by replacing pads and rotors all around. I also replaced both passenger calipers and hoses. I also replaced the caliper on driver side front. My wife has driven it 5 hundred miles since. Still smelling it on steep long hills. Today I replaced master cylinder and rebled everything. We took it on a long drive ( around 40 miles ) came up on steep hill that takes us home and they stunk on top of hill again but cooled off by the time we made it home. It has 235/60R16 tires all the way around it. No lights on the dash at all and it has 73,000 miles. I'm at a loss please help.
