Oil or hydraulic fluid?

Is it the calipet or the hub. Caliper isnt good as its brakes.and hub osnt great but better than caliper you need to remove caliper and find out b4 road test id say.as bo brakes wouldnt be nice

Check the level of the fluid in the master cylinder.
This needs addressing ASAP.

Just be advised that if it's the actual hub oil seal that's leaking then you are in for a bit of an issue... all of the seals available on the market seem to have an incorrect inner diameter, don't know why, it just happens to be the case. You need to try and get hold of an old stock corteco seal. I know someone on the D2BC forum who is importing these especially, but don't know anywhere stocking these.

Which passenger side - front or back??
