My rig is a 1998 2 door 4wd with about 250k on the clock. Last time I did a front brake job was in August 2010 and about 57,000 miles ago. I used Baer drilled and slotted rotors and the Hawk green box LTS pads. There is significant uneven brake pad wear between the inner and outer pad. As seen in the picture the caliper side has lots of pad left. The other/outer side, not so much. Is this normal?
