Man, I thought I was hard on brakes :-laf
I've got 55,000 on my dually, towing most every weekend, and mine look like they will go to 100,000 pretty easy.
I didn't check your signature before I responded, but I use the transmission for stopping and I also run my trailer brakes pretty tight. Between engine braking and trailer brakes, I believe the "stop and go" unloaded I do through the week is harder on brakes!
Anyway, back to the post, I've used the performance friction pads on numerous occasions with good luck. They aint nothing like the Wilwood stuff I used on my sprinter, but they don't cost as much either, lol.
