I would be tempted to change the Slave for an MPL one, and take it from there.
The blackening of the fluid is the lines along with the seal.

if i change the slave its not going to help with the master . i forgot if you look where the the lever pushes the piston on the master then you can see a wet patch where the seal is leaking
There is no repair kit for the oem M/C i'm afraid.
Black fluid is common to all Brembo oem systems, you won't fix it.
i wouldn't buy another oem M/C if you go that route. buy the forged or cast version for 2 reasons
1. They do rebuild kits @ £35
2. it's much better quality an doesn't let air in.

Also, mine has a diaphragm in the M/C, and all the tech docs do NOT show it, just the resevoir, the gasket (seal) and the lid...
http://www.ultimateparts.net/aprili...001,2002-Aprilia-Spare-Parts-Genuine-&i=18143 - Item 23 / 24
I did try it without the diaphragm (it looks like a semi-unrolled condom) and it leaked worse..... :s
Any ideas?

Aprilia do not sell spare internal parts for OEM M/C.
your choices are to replace the whole unit or visit a dealer for a manufacturer that does sell the parts. KTM sell some Brembo spares (dust boot) and the M/C main seals can be had from Honda (not a brembo part but a match size wise)

Cheers, Spoonz! Any idea what the Honda bit is, ie what bike it's for, mate? Thanks for your help.
I have the part numbers somewhere so will dig them out and post up when i find them
KTM/Brembo Dust boot - Called a "Rubber Cup" in their parts list is Pt no - 61013008000
M/C main seal - Honda CB900 RRW 98 (amongst other Honda models) Called a Master cylinder repair kit - Pt no -msr-106
Ktm sell the parts as they signed a liability waiver with Brembo for diy fitment of the parts. Aprilia etc won't sign it so Brembo will only sell them whole units and external spares
