135. 000 miles of HARD towing in the MTs of the west on my 04 and finally did the first brake job today. Very happy with that kind of service, typical combined weight is between 19,000 and 24,000#. I do have a PacBrake and would not be without it. I upgraded to Baer slotted-drilled rotors, with Hawk Extreme HD pads. Got reman stock calipers. Will do the first tow next week, kind of excited to see how it goes. OR STOPS I should say.
