Hi All,
After living for a while with front brakes that were still spongy I have decided to sort them out once and for all. I took the entire system off the bike and cleaned the parts. Taking the master cylinder apart I found that the bore is slightly scored. Not much, but still visible. File comment: Master cylinder bore

Is this going to be an issue or should the seals be all right to keep things working properly? File comment: Master cylinder parts

I have laid out the parts I took out of the cylinder (top row) and the replacements from the Brembo kit I bought (bottom row). The old circlip was mounted over the top of the dust seal. I'm assuming that is not the way it should be?
Of course the helpful instruction sheet that comes with the kit shows slightly different parts!

The instructions tell me to install the primary seal, which I assume is the rubber seal (nr 25), with the lip towards the interior. Does the lip mean the 'open' side?
The same goes for the secondary seal (the white plastic ring, nr 27). Is the lip the side with the larger outside diameter?
Together with the kit for the master cylinder I have new seals for the calipers and new Brembo pads. Hopefully this will get the brakes up to scratch!
Cheers,
Mike
I was fiddling with the images to make them fit better on the page. 
I only wanted to post the modified picture so one can see what you mean. The original is a bit dark.
