When backing up and applying the brakes, you may hear a squeaking noise. Scion engineers addressed this problem by modifying the shape of the brake pad and the anti-squeal shims; they also applied more grease during assembly.Google+

Happened right after brake pads were replaced by the dealership. "Brake service" did not fix. Squeals first thing in the morning when backing down driveway and at first braking of the day. Worse when weather is wet and freezing. Does not happen if weather is dry or warm. Sometimes happens when making a turn early in the day.

My brakes have been squeaking when I was in reverse, but I checked the brakes as had my mechanic and nothing was wrong with the breaks. I just live with it...
I HAD NEW BRAKES PUT ON MY CAR. AND IT ALSO HAD THIS PROBLEM.I TOOK IT BACK TO THE DEALERSHIP 2 TIMES AND THE FIRST TIME THEY CHECKED IT. AND SAID THAT THESE CARS ARE SUPPOSE TO MAKE THIS NOISE. AND I TOOK THE CAR BACK THE 2 TIME. BECAUSE I GET A CALL SAYING MY PARTS WAS IN FOR MY CAR. THEY DID NOT TELL ME NOTHING ABOUT THEY HAD TO ORDER SHIM FOR MY CAR. ANYWAY THEY REPLACE THE SHIM AND THE CAR ARE STILL MAKING THAT SAME NOISE. I CALL THE DEALERSHIP. AND TALK TO A GUY IN SERVICE DEPARTMENT. AND HE SAID IT ONLY WILL STOP SOME OF THE NOISE NOT ALL OF THE NOISE. I WAS NOT HAVING THIS PROBLEM AT FIRST. PLEASE TELL ME WHAT I NEED TO DO NEXT.I JUST WANT MY CAR BACK RUNNINIG LIKE IT WAS BEFORE I TOOK THE CAR TO THE DEALERSHIP. THANK YOU
