Squeaking Noise When Applying Brakes in Reverse on Scion xB

Problem Description and Possible Solution

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 and getting louder squeak/squeal in brakes (rear?) on reverse. Mechanic says brake shoes and pads are fine.
2005 xb in great condition, brakes squeak braking on rear only. will investigate, air in line seems to be part of the problem, also seem to be uneven line pressure to the rear wheels etc..
same thing squeaking, and I had the brakes checked and they are good. I've only had the car for 5000 miles. purchased from a certified toyota dealer. sounds like toyota needs to do something about this problem.
I bought this car in 2007 with 10,000 miles on it and it would squeak quietly and only every so often. I took it in and they said it was fine. It kept happening and I needed new tires, so I bought four new tires and got an alignment… It kept happening. Around 2010 it became every time I applied the breaks. Now, it's 2016, 190K miles, and even with new breaks and new tires [again] it happens even when I'm not on the breaks.
Just recently when i back up my rear breaks does a noise like a squeek and i had new breaks installed a few months back. I had my car in the shop and mention and they said they would take a look but is still doing it.
my brake shoes make noise when stoping replaced brake drum same noise again and shoes. the brake shoes were wore on the ends now its making same noise again thier was plent of pad left but both ends wore again
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????
