I swapped out my pads after 28,000 they were down to nothing. I bought the OEM pads but there were no sensors or squeakers on them like the originals. They were the more expensive pads from the dealer. The fronts lasted 24,000. Also I was disappointed to see the boots on the pistons burned or disintegrated. This happens on my car I road race but the truck? Is this normal? I don't remember the fronts being like that a month ago. Also the pads were very corroded after 18 months. Thanks for any comments.
