Wife has a 2011 Rav4, 28k miles brakes have started making a horrible noise, doesn't sound like traditional metal on metal and the pads have a 1/4 inch left. The noise sounds more like nails on a chalk board than anything. Only at low speeds and light braking... usually the last 20 or 30 feet of rolling to a stop. The local Dealer has a reputation for avoiding warr work and always come back with the unable to duplicate BS. This sound familiar to anyone?
