I'm the original owner of this 2011 RAM 4 X 4 .It is a low mileage truck, 32165miles. With that, I have replaced the passenger side front caliper twice due to it seizing up. The second caliper froze up again today. The first caliper had frozen pistons. No brainer there that it needed replaced. The caliper that froze up today, the pistons are free!!!! I can depress them very easily. But the caliper was froze to a point that the rotor was smoking. Has anyone else having this problem and what did you do to correct it. It seems to me that the current problem is not the caliper, but something up stream.
