Good afternoon, while my daughter was driving the car she heard a pop at the ass end of the car. She stops and can't see anything wrong. Starts to driving back to the house and when she puts on the brakes she hears a scrubbing sound. Gets the car home I jack up the rear of the car and when I take off the passenger side rear drum off parts fall out. Are there any actual pictures of the rear brake setup not a diagram that I can look at? Any and all help would be greatly appreciated and thank you.
