. I seem to have a small amount dripping form the forks and onto the front brake (like the odd drop: nothing major).
Sam,
might be helpful to post a picture of the oil on the brake, if its getting into the brake hub and onto the pads obviously very bad!
Leaking fork seals would fail what we call a Warrant of Fitness over here and force us off the road until remedied.
If just the odd drip a regular wipe over is an option but would be worth checking the fork oil levels as a lack of oil won't assist your road holding as the bike will lack damping.
If overfilled they also tend to leak and I recall mixed oil volumes mentioned in various literature. Also pays not to run light fork oils.
Assuming its got a leaking seal the worry is corrosion on the fork stanchions from moisture in the sliders. If pitted they quickly eat seals and need replacing,
Could just be a matter of old seals, a fairly cheap and easy fix if everything else is in good order.
If pulling off the legs you will need a fork seal removal tool, usually made from an old pit of scrap pipe so you don't damage the seal holders
