So it uses brake fluid and the booster can is oily were the mastercylinder mounts...
"What looks like a duck and walks like a duck must be a duck"- type of fault.
- Is my booster full of brakefluid? ( if so, does it also need replacement?
- Is my aluminum master cyl rebuldable or should i get a new one?
- Any other problems around the rebuild/replacment tha will pop up?

Try to determine if brake fluid has entered the booster. It would pool at the bottom and a dipstick of sorts could be used as a check.
Conventional bleeding should be OK after the cylinder is bench bled, just don't let the ABS HCU run dry.
No aluminum m/cyl rebuild kits, replace it.

Thanks Imperial, the abs hasent run dry and it still functions.
But i have to fill the reservoir once a week and the pedal is a bit spongy
so its time for replacement anyway.
- Does the booster stand brakefluid? if so i can just suck up whatever thats inside.

If brake fluid gets into the booster, it cab deteriorate the the diaphragm inside and it can also be corrosive to the booster's shell as it eats the finish off. However, the fluid can also just be sucked right out of the booster by engine vacuum and burned with little damage.
