The little rubber o-ring on my Formula Oro caliper (the one behind the little grub screw) is looking a bit worse for wear when i was bleeding them earlier- anyone know the o-ring dimensions?

Thanks in advance!

Wishing i'd measured the thing before I put it back in now, but it was a bit crushed.

I think they are 2mm ID, 1 mm thickness from a bit of internet trawling. In which case, they are about £8.56 for 100 from these guys [url= http://simplybearings.co.uk/shop/Seals-O+Ring+Seals-VITON+O-Rings/c19_4501_4706/index.html ]click[/url]

I was hoping someone would confirm the size before i buy a load of them! The cost of the Formula o-ring replacement kits is ridiculous, so will try the ones linked to above if they are the right size.

Cheers, fakesounding; looks like that is the right size. Think i'll try the bulk order ones, see how they go.

The full oring kit is silly money but this is all you need:

Afraid I can't conform which it is you need though, I think it's the 2mm but I'm not 100%. OK, it's still a lot for what's probably a 2p part but it brings it into the realm of the sane.
