I had to do a quick and dirty front brake pad replacement Sunday (and missed a ski day to boot) all because I never heard a noise from the brake wear indicator. I know that front pads wear quickly, so I've been checking them from time to time, but I assumed that I would hear a noise like on every other car I've owned. Well, I did hear a noise, but it wasn't from the wear indicator - it was metal on metal - no pad left! Minor scoring to the disk - made do w/cheap pads for now. Will do a proper repair in a few weeks. The old pads were Aisin, and had the wear indicators - with scoring on them, so they were dragging on the disks. Is this uncommon? Should I visually check on a regular schedule? If this is not uncommon, then I recommend you all go check your pads now! The pad replacement was only barely harder than an oil change by the way - no excuse for letting it go. Hopefully my mistake saves somebody some $ and irritation.
