Following on from:16273- I have removed, cleaned,refitted and bled the entire brake system and topped up to max. But pedal travel still excessive and every-time I bled the brakes air was still in the system. servo unit ok as brake pedal firms up when car stationery engine on or off. Could this be a problem with the master-cylinder? but how is air still getting into the system, any ideas.

As suggested by wittinghame possibly master cylinder,you could try a pressure bleeder in case a seal in the cylinder has been flipped slightly with brake work.

This may sound silly, but did you remove the callipers and accidentally refitted them on the wrong sides.
As if this has happened then you will have the bleed nipple at the bottom of the calliper then therefore you will not be able to remove the air from the system as the bleed nipples need to be at the top of the calliper to remove the air from the system.
