Now this is no help at all but.....

My brother's Daewoo Espero suffered the same problem. We bled the system thoroughly (pressure bled with about 5 litres of brake fluid). We found out how to bleed the ABS unit and bled that. Very little if any air came out on any of the bleeding operations.

Then he replaced the master cylinder and bled it all again.

Still not right, but just good enough to pass the MoT.

Still at a loss as to the root cause. We're thinking duff replacement master cylinder or some kind of servo problem.

Well, bled the brake 'till I'm blue in the face today, still exactly the same. I'll go for the master cylinder seals next - bet you can't get a repair kit!
Maybe the best answer is to buy another car cheap - just for the spares!

Could be air in abs unit - a real bugger to get out, needs tech2

Needs Tech 2?  Enlighten me....  does the tech operate the pump / valves etc.... Read this on several posts...  never really thought about it until now :-/
