Hi guys,
One of the seals on my caliper is leaking very slightly. It has been converted to O ring pistons/seals.
The leak appears to be coming from a damaged top seal, the one that fits over the piston and seats into the caliper.

My question, is this seal the same size in both lip seal kits and O ring kits? I have a spare lip seal kit and was going to use the one seal from that if it's the same size. I'm in th UK so I can't just go to a local parts store and the specialists only have the complete conversion kit or the same lip seal kit that I have.

Appreciate any help.

Take the piston and caliper to a reputable hydraulic company they will be able to supply an oring to suit

Pretty sure the O ring is ok, it's the actual seal that has a pin ***** hole in it.

If fluid is leaking from the "top seal", the one that fits over the piston and seats into the caliper, then the o-ring seal is leaking. That top seal is just a dust boot.

Of course it is! Must gave been having a brain freeze! New caliper on order, thanks.

Make sure that you tell the seal guy you need an EPDM O ring.

The normal O rings will not work with brake fluid.
