The front wheel was dragging on the brakes when trying to turn it with it suspended. I removed the disc pads, took the calipers off the bike and cleaned all the dirt and dust from both with brake cleaner. I also pumped the pistons out a little and cleaned them up as well, but didn't split the calipers at this point as all the pistons (with a little toing and froing) seemed to move reasonable well.
I copper slipped the leading and tailing points on the pads as well as the backs and the holding pins before reassembling it all. But you've probably guessed it, they're still binding.
The next step was to split the calipers to see what the seals were like. I was expecting (hoping) to find some corrosion once the pistons were removed, but nothing
Even under the first dust seal I removed it was like new under it.I am now wondering if the pads are somehow not free enough in the calipers, although they don't seem to be a tight fit when sliding them in (oh err missus
) now I've cleaned them.Does anyone have any ideas where I go from here
Any advice would be very much appreciated
Chris.
