In the past I've burned off contaminated oil by hard braking or extended brake dragging. I've not had this long enough to sort it that way but each time I stop, there's more black stuff on the disc rotor so I guess there's lots of oil to burn off.
Okay, I'll pull the pads out and knock a layer off before hosing them with disc cleaner or IPA (not that kind).
Any preference for sandpaper grit or should I just use what I've got? gets metal file out :)
I have this issue currently with a leaky Shimano caliper (going to replace it with Hope as I'm fed up).
Heat does indeed kill the noise for a wheel, I don't know why.
Contaminated pads - my current pre-ride routine demands I sand down the top layer of the pad which has got contaminated, and clean pads and rotors with IPA (not that kind). It's fine for a ride and then the caliper leaks again.
