Leaking caliper

[yellowdog]

I suspect I have a leaking caliper on my xs2,
Not much just a little wet underneath ,I think it is coming from the small o ring that is at the top of the caliper, the one in between the two halves ,the original one is a square section o ring whereas the one supplied
with the rebuild kit is a normal one ,it was a little smaller than the original.
It's very hard to tell if that's where it is coming from but I don't want to risk it.
Can I get these square section ones in the UK or does anyone have any suggestions .
Thanks

Reuse the old one, at least as a test.

I know this doesnt answer your question but I saw your thread on the rebuild of your master cylinder question but never did read which rebuild kit you ended up using. I just ordered mikes rebuild kit for my '72.

This is a pic of the m/c rebuild kit I used ,got it from Yambits UK.
Believe this was a right pain in the bum because the top hat refused to fit over the piston head ,I had to buy three more before I finally managed to get it on because they kept on splitting ,it is a very tight fit .
And just as I thought it was all ok with the brakes I now have a suspected leak.
5 twins ,yes that is I will do just to check if it is that o ring problem.
Thanks
