Yeah, Saran wrap which I mentioned for under the cap is just a brand of plastic kitchen wrap here. Regardless what it's called which side of the pond you're on we're on the same page as far a creating a liquid vacuum like a straw.
I've heard you don't necessarily get air in the ABS HCU (hydraulic control unit) by disconnecting the lines going to the different brake locations but it's the lines between the master cylinder and ABS you don't want to go dry/let air in.
