recently ive had the windows down when drivin and ive noticed that at about 10-15 mph and turning right there is a squeaking noise. its on...off...on...off...on...of like something catching something thats warped, must be the brakes but its had a service not long ago and they said the pads were only 50% worn. does any1 know what it might be? it doesnt do it any other time apart from turning right even when braking?
