I did a front pad slap on my Ram dually at 100k miles. The original pads still had some meat but they were rock hard and their performance was poor. I used Bosch pads I bought from Amazon for $39. I really like these pads, initial bite is smooth and progressive, much better than the 100k OEM pads. Can't say how they will wear but for 39 bucks and a couple of hours of time I will replace them again.
Many feel that the more you pay the better they are. I disagree.
