had my 04 euro serviced a month ago in perth, drove 400ks home and have only done ~100ks around town since (car has done 42000ks)..

mrs took the car out yesterday to go into town and on the way back it started making a horrible squealing noise when moving (forward and reverse) without having the brake pedal engaged.

it was really high pitched. i took it for a spin not long after to investigate and it only did it when i reversed out of the driveway and then didnt do it again. ive driven it around town again this morning and it hasnt done it.

im going to call the mechanic on monday and ask if they checked the brakes (report says they did).. does this sound like brake pad squeal? why would you hear it when the brakes arent being pushed?
