i own a 1996 s420. everytime i break while im in reverse the breaks squeek. when im going forward and i break there is no sound. i only hear it when im in reverse. i just got this car over the summer from my parents who've been driving it on a daily basis. i do not know how old the breaks are or when they were last changed. ive asked some of my friends and some jus say dust, and others say i might need to change em and some say that its jus cuz im half breaking. does anyone have any ideas on what is happening?

 

get your rear pads replaced. and please replace them with factory parts no aftermarket junk please i dont care if there 40 bucks cheeper.
