Spongy brakes

[Bowline5]

Last week I set about fitting new front pads, I've done it many times on many cars and it usually take longer to jack the car up and take the wheels off than it does to fit new discs. Not this time. The came out easily enough but the calipers were so corroded, and the slide pins jammed solid, that new calipers and carriers were a necessity. Of course the final job was bleeding the new calipers out, made harder because my old Easibleeder would not fit on the master cylinder. It works now but is still a little bit spongy so will need more attention very soon; my car, an 2.5 turbo, has a two line system, is there a specific order in which I should bleed? I clamped the pipes when changing calipers and only lost a very small amount of fluid, then reverted to the traditional sequence of starting at the furthest point from the master and finishing at the closest, in this case left wheel first then the right. If the two lines are a diagonal system should I worry about the back wheels at all, if so in which order.

Just in case I've looked at the master cylinder, I cannot find its equivalent anywhere on the net. It has two pipes on the right hand side; every two pipe master I've seen, and there aren't many, have one on the right side and one at the end on the top surface. Surely I can't be the only one!

Any thoughts or advice welcome.
