[Red Herring]

Just goes to show you're never to old to learn. I've just read up on the various Mityvac kits you can get and they are certainly a useful tool to have, and if I was running some kind of commercial operation I'd almost certainly buy one. Unfortunately at upwards of £80 for the suck/blow models they're quite an investment and given I probably only drain, flush and refill brake systems half a dozen times a year probably not worth it for me so I'm going to stick with my £2 syringe as it seems to do exactly the same thing, although admittedly it's a bit more of a fiddle.
