Hello everyone! I just got a 2006 Scion xB earlier this week, and I have been loving every minute of owning this car! However, there was an issue that I just had come up. I was noticing that when I was braking at low speeds, I heard a sort of creaking sound coming from the rear of my xB as I was about to stop. I want to say it might be the brakes, but I'm not entirely sure. Any ideas on what it may be? Thank you!
