Hi Colin, My 2007 4cyl Rav rear brakes make a sort-of chirping noise, but only when driven cold, and in reverse? It goes away when the car warms up? I can't figure it out.
Can you get this squeak just sitting in Park and pressing the brake pedal or do you have to be moving?
If you have drum brakes in the rear, the squeak is most likely caused by a lack of grease between the backing plate and the corresponding point on the brake shoe.
