but he's still got pad left Ken,
so I'm thinkin' it's just accumulated brake dust, road dirt, grime.
hard to tell from the pics, but intermittent grabbin' and no signs of overheating.
I'm bettin it's grime.
The red tape idea's a good one tho,
think I'll start doin that.
Having a new front tyre fitted can cause Rotor distortion.. if the tyre fitter doesn't mount the wheel correctly on the tyre press..
I always run RED tape around the rotors at tyre change to remind the heavy handed B*&^%rds to take care of my Brake Rotors..
