The other day, at 107,000 miles, I heard the indicator on one of the rear brake pads hit the rotor. I wound up replacing the rear pads and rotors. Nothing out of the ordinary until I went to inspect the fronts, they were like new (see pic). I understand the brake bias has changed over the years and the rear brakes are much more engaged, but the rears were toast. I have owned the Jeep since new, drive like I stole it most of the time and tow a utility trailer often. It is a six-speed and that helps, but will I ever have to replace the front pads?
