So like everyone else my break pads don’t last worth a crap. I was looking at the pads on my quad and noticed little chips on both sides. I got to thinking and decided that small rocks and sand must be getting stuck in the holes in the disk. Ones the rocks are in the disk they get dragged into the break pad tearing away at it.
Now if we had disks that were just smooth or at least only grooved these rocks couldn’t get in and damage the pad.

Can someone explain the flaws in my idea here. I can’t see what’s wrong with it but I can’t find smooth or grooved disks anywhere. Everything I find is holed or slotted.
