weird brake pad issue

Job done

Just to let you all know, I have replaced all the brake pads and all is well. I checked the rotors for free play and they are in good shape.
Thanks to all for the advice.

R3 brake q

I have an 05, I've had since new. I need much stronger brakes. Are their options? I'm buying another R3, to customize and add a turbo, so I know I'll need better brakes on that gem.

Any suggestions are appreciated!
 

also beringer makes some amazing rotors and calipers .
