Hi, first time here. My 2008 Camry LE makes a hammering sound as I slowly roll to a stop light while gently braking. This is intermittent but occurring more and more frequently. I've been told this is due to the sensors in the antilock brake system. Is there any diagnostic alternative to checking the brakes at each wheel to see which sensor (or sensors) are the problem? I had someone look at the car but the problem didn't occur while they had the car and they didn't get any obdii codes.
