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?
