Anyway I tried to bleed my brakes this afternoon. I thought all was going well, I followed the video to a tea. Fitted to my bike and it hasn't worked. The level moves all the way down, even when the pads are almost touching. Now I know this means there must be air in the system still. I've removed them and bled them again, also checking for leaks. There is no air coming out of any of the lines, or unions or any of the bleeding points. Does anyone have any Ideas?
