My 07 Sienna has 41K miles. I'm wondering if the front brakes need replacement. The owners manual says it comes with brake pad wear indicators that give off a "squealing or scraping noise while driving." I've noticed a soft, pulsating scraping-like sound when the brakes are applied, especially when 1st driven and am wondering if that sound is the wear indicator. Don't hear it all the time. On other cars I've heard, the wear indicators generated a loud, high-pitched scrapping sound. That's not the case on my Sienna. I pulled the tires and the pads look okay to me, but there is only an eight or 3/16 inch clearance between the rotor and the caliper bracket.
Anyone have any experience with this. I'm guessing I ought to have them checked.
