Lubricant spill on disc brake As the title suggests, I was lubricating the gears and chain, and I accidentally dropped some of the oil on the rear brake disc. I didn't notice it then, and took the bike out for a spin. That's when I noticed the rear brake was acting funny. Problem, there is oil all over the disc, and maybe on the brake pads too. Any suggestions to solve this?

Clean rotor with detergent, dry, clean with meths. Replace pads.

Some people have methods for degreasing pads but i find none of them satisfactory.
