    Hello experts when I break I have been hearing like a thump coming from the rear.
    I thought I had like a heavy thing loose in the spare tire compartment.
    Now, few days later every time I break, brakes make like scratching noise again it seems coming from the rear? Could it be drum issue, any ideas?
    It also does it when I back out the driveway.
    Where should I start troubleshooting?


    Thank you in advance for your wisdom!

    If you feel your brakes are causing the issue, you can get a free brake inspection at many auto service shops. I think you should have them check it out and you can decide what you need to replace.

    Some slight grinding/scratching noises can come up after the car has been sitting in the rain. If you do a few brake cycles while coasting in neutral, it might solve your issue.

    Where are you in "usa", in the rust belt? What's the miles on it? Presumably you've thoroughly checked the hatch area, taken off the floor, under-floor tray, inspected the spare and tools, and 12 volt battery is secure?

    Thanks so much JC, yes it's been raining 3 days in a row and no garage.

    Hey Mendel I'm in South Carolina. Yes I'd inspected the hatch, battery and so on. So the thump is still a bit of a mystery.

    i would take a hard look at all the rear suspension components. how is the rust situation underneath?

    thank for the reply. The thing is this noise happens even at very slow speeds like coming out of the driveway. So I would not think it is a suspension issue. But tomorrow I will do some testing. For sure there is the rain component that explains the squeaking noise. As far as the moving body I guess I may take it for a free brake inspection. I already looked at the front pads and they seemed to have still quite a bit of life.
