100-200 miles. no more.
I felt like mine were taking a little too long, so I flushed out all the brake fluid, pulled the calipers back off, pulled the slider pins out and sanded them down some to clean them up, knock off the crud, put fresh axle grease on the pins, and a light coat of grease where the pads slide back and forth on the bracket, and reassembled everything. no more dragging or hot brake smell after a short drive.
I tried to be lazy, knowing that I probably SHOULD have done all that when I swapped out the pads. I ended up having to tear it all apart and spend another 2 hours re-doing my work!:jester:
