Brooke Nelson (Oak Park, Illinois) - 1997 Chevrolet Lumina
When Brooke puts her car in Reverse and steps on the brake, she hears a loud moaning/Tarzan scream noise. It goes away once she starts going forward. Not sure where the noise is coming from, but it’s very loud, and it’s been doing this for a year! Her dad’s a mechanic, checked the brakes and said they’re okay. Tom and Ray think the noise is brake-related--likely the parking brake not releasing entirely when she first stops, and the noise is the caliper rubbing. Also, possible problem with GM after-market brake parts.
