My 2013 Prius recently started making a squaling noise when accelerating at low speeds. My rear pads were just replaced about a week ago but the front ones haven't been changed for at least a year. I replaced the water pump yesterday because I had been leaking coolant and getting the P261B code but now my car is squaling worse while driving ( foot off the brake) and it handles like I have a flat tire but I don't. It sounds like its coming from the front passenger side wheel area but I'm not sure. I'm going to post a video
