I get that mate, if it's mobile at least you can move it if you need to. We sometimes get a long stayer in at work and they can be a pain.

ps. When you get back to it try clamping all 4 flexible hoses off (assuming you haven't fitted stainless steel ones?) and see how hard and high the pedal is. If you can get someone to keep pressure on the pedal and then you release each clamp in turn and see by how much the pedal drops. That should point to where any air might be lurking in the system mate.
