    Prius V rear brakes squeal when backing up. Any ideas why?

    A lot, always, or just at start up for a few seconds?

    Yes, the parking brake is fully disengaged. It squeals every time, on startup.

    Only backing up... could be normal.
    Steps to reduce brake squeak include:
    1) Deglazing the rotors.
    2) A few high speed stops, with cooling between stops.
    3) Reapply anti squeak "grease" to the pad backings.
    4) "Blue Printing" the pads.
    Good luck

    Thanks guys! I guess it's not too serious then. When it goes in for maintenance, I'll ask the tech to check it.
