I've done some looking around but I can't seem to find anything relating to this so here goes
Hopped on the bike this morning to head out, started to roll and hear a horrible scraping coming from the rotor/front wheel area, hop off, take a look, there seems to be a small, maybe 2mm x .5mm (long in the path of motion as the pad runs across the rotor) section of rotor chipped and bent out (attached section along the long side) so that its sticking out and scraping across the pad. Get out the leatherman and attempt to do something, end up pushing it back in, which makes it happy for a while. Soon enough however, and throughout the trip it sounds like the chip is being partially pulled back out and is scraping across the pad and then gets pushed back into place.
On return home I can see the chip in the rotor but I can't seem to get anything underneath it to bend it out and possibly file it off. Looking at the pad on that side there is a 1 x1 mm wide and deep groove cut out of the pad where the chip ran across it.
what can I (or should I) do about the rotor? try more to remove the chipped section and remove and protruding metal from the rotor and risk scraping up the rotor more?
at what point do I need to replace the pads? There is probably 2mm of pad thickness overall, with .5-1mm left under the scraped section
I'm running shimano deore hydraulic disc's with 160mm rotors
