Squeaking Noise When Applying Brakes in Reverse on Scion xB

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.

My breaks has been squeaking for about 2 years now, i have told the dealership over and over when go to service my car. They make excuses like, maybe its dusty or maybe your brake pads need to be changed. ive since changed my break pads but still it squeaks.

Loud squeaking noise occurs when applying brakes while baking up. Took vehicle to Toyota dealership and told it is due to moisture on brake pads. States everything "looks fine". Problem continues even on dry days. When googled problem seems many other Toyota models report this same problem. Technical Service Bulletin sent out regarding Rear Brake Squeak (T-SB-0098-10) to service mechanics notifying that Some 2010 Prius vehicles may experience rear brake squeak when backing up or moving forward during the first few brake applications when the brakes are cold. An updated rear brake shim kit is available to reduce the likelihood of this condition occurring. Could this also be a Scion problem????
