Brake fluid hose

Hi, firstly is this the correct place for braking needs? i think one of my hoses that joins the resevoir to the master cylinder is leaking as if i touch the hose it leaves my hand slightly greasy like brake fluid although nothing drips. The hose has a proper clip on it to seal aroung the reseviour barb outlet and the same on the end that joins the flared copper pipe that meets the cylinder. I am sure the hose im using is the correct stuff (rubber hose with fabric braiding) from merlin motorsport but i would have expected it to last longer than 8months. What is permanent solution for this if i need to replace it after some more checks?
Thanks
Adam

there was a thread about this recently. Are you using fully synthetic brake fluid (DOT 4)? As this is what the fabric covered hose is designed for.

Shouldn't be anything wrong when basic DoT4 unless you are generating hooge amounts of heat and then you'll need something like AP600 (DoT 5.1). I would be very impressed if you can generate these sorts of temps in a lightweight car.

il check it over this weekend as maybe its just from the initial bleed when it all got a bit messy or something worse like a sharp edge on one of the flared pipes from the cylinder. The brakes have had an easy life so far and even when it does get on the track i doubt we would be able to get it hot as we'd be too scared of pranging it
