Never really had the noise, but the factor pads are messy when it comes to the dust. I got Ferodo pads on my bike now. Work great and no mess.
The dying whale noise means you have completly glazed the pads. Sorry, you don't win a prize for this. The other squil like a girl noise that comes next is from that glaze burning. Easy fix, pull the pads out, rub in circular motion on semi-smooth concrete, wash off and re-install.
But why would you, a lump of wood would work better than the OE pads!
Here a thought. Now that I have saddle bags I could store a lenght of rope and a ancore to toss out at red lights, couldn,t be worse than standard brake pads.
Are you supposed to use the front brakes?
