i think i have a prob

[andy76]

when reversing in gear is fine but when i brake in reverse or coast backwards im getting a loud humming noise from the passenger side rear wheel.
sounds like and old bus, it's that loud that it woke my 2 yr old up in the car.
any help would be great....

just forgot iv'e looked at the rear discs and the passenger rear whats making the noise has like a scored ring on inner side of thr disc....

Sounds like stuck pads,get new discs and pads,and have plenty of good 'ol copper grease shoved on them!!!
