On an '08 Nissan Xterra s with only 17,000 miles, the right front inner brake pad was completely worn down and made metal to metal contact with rotor, ruining the rotor. The vehicle was pulling badly to the right when the brakes were applied. Only the inner pads were affected,the outer brake pads looked like new, showing that the brake caliper was stuck on the bracket. Took to dealer and they told me that the 2 inner pads, left and right, were stuck in the bracket, which stops the caliper from floating or moving. At 17,000 miles this should not happen and is a potentially dangerous problem. Nissan has refused to repair under warranty and refuses to acknowledge that my invoice says "both inner pads stuck in calipers".
