i have a 2007 Sahara with 56700 on the odometer. today i was gonna replace the pads because i figured it was about time. I started in the rear and both sides had even wear and were due for replacement. The front still had slightly better than half the pad left. now i have a manual tranny and i know that helps but is that common or should i have the brakes looked at. i just think 57k on the clocks would be a lot for brakes and especially to have half a pad left. thoughts?
