GS1100 front caliper o-rings?

[Hambo]

Anyone know the specific size and material of the o-rings between the two halves of front brake calipers on a GS1100? Now in Ushuaia with a leaking caliper...hope someone knows!

Cheers, Hambo

They are not shown ...

... on that schematic because they are internal and only visible if/when you split the caliper.

ISTR they are about 7mm across I found out the hard way by reassembling the caliper blocks without them, having discarded them in the crap. Found them after a painstaking search of the gutter where I had flushed the crap
