I just now turned 21,000 miles on my '05 XB, and today I am hearing what sounds like the indicators on the front brakes starting to scrape. Could it be time for new brake pads already? Seems kinda early! Has anyone else gotten to this point with their brakes yet? Just wondering what the average lifespan of brake pads on the XB's are? I am at exactly 21,160 today. I will be checking them visually tomorrow.
