Re: 2005 K1200LT Front Brake Pads
The groove is there so people will ask questions!
Most rotors have groves and or holes to conquer the off gassing and cooling issues associated with braking. I have seen friction pads in various applications with this done for the same purpose.
However, in this case the groove in these pads is simply for you to know when to replace them again. When the grove is no longer visible its time to replace them.
Bonded pads I believe can run as low as 1/8th or 1/16th of an inch...you can use a drill as a gauge to compare the remainder of the pad beyond your groove to the steel backing. Then you can tell us all what you found.....
