Hello, I removed the rear wheels on my truck just to inspect the condition of the rear brake pads and was surprised that it looks like maybe 25% lining remaining on the pads. My truck has the original 26,300 miles from an older one owner man. He never used the truck for any real work (hauling or towing). I usually always get well over 80k (got 175k on my T-Bird) on the rear pads on all the other vehicles I have owned. Is this kind of wear normal? BTW, the front pads are factory original too and look like they have approx 50% lining left. Thanks!
