Purchased a 2014 RAV4 certified the brake have a clunking noise in the right front bake caliper when you stop hard. in the morning backing out of garage their is a noise after brake pedal is released and pads are noisy. Dealer checked everything out and said brakes were fine all is good,took a dealer tech for a ride 3 days later and he heard the clunking and noises.. They called it pad rock when i stop harder on the brakes, all other brake noises are normal for the RAV4 they all do it. nothing wrong with pads or hardware, it 23,000 miles on it,any ideas beside just drive it.
