Brake discs don't seem to be smooth
Recently been hearing a droning sound as I slow down in my GT, presumably coming from the brakes. On inspection it seems my brake discs are slightly warped as when i run my fingers over them they don't seem to be very flat. Perhaps needing replaced???
The pads were replaced a few months ago & the brakes work fine, but does it sound like I need to replace the front discs? Does this also sound like the cause of the droning noise that seems to be loud when I first apply the brakes then quietly fades away as I slow down to a stop.
Hope somebody can shed some light on this.
