Discovery 2 year 2000 td5 with abs sls etc. After a sequence of very heavy braking, brakes red hot and allmost gone all together, I then lost a firm pedal and whilst it will still stop the car. the pedal under pressure goes slowly to floor .There are no leaks.The old fluid has been completely replaced. Replaced master cylinder, no change. replaced flexi pipes for goodrich ,no change. brakes been bled using two man method and pressure bleeder, no change.There are no abs lights on (and the bulbs are working) Any Ideas greatly appreciated

Sounds like your pads have glazed through over heating, try changing them there only £10 a set.
Oh and your brakes might have over heated cos yeh disc are below the wear limit!

You might have fried a seal or two in your brake caliper when over heated that's letting a bit of fluid out!
If you dive on the peddle fine style and keep it pressed (which you never do while driving) it will go down a lot!

I have blanked off each caliper in turn from the system to check for this, the pedal was consistent with each caliper blanked off in turn,no fluid to be seen at calipers either. It only takes light pressure for pedal to drop when servo in operation,when not running there is more resistance but pedal still falls.

Were brakes OK before you over heated them and how exactly did you, were you going down a mountain or summet?
The only thing that I can think of is that you boiled yeh brake fluid and summets gone in the abs unit or your new master cylinder is duff (Not impossible)
I think that it is likely that some thing has gone in abs unit (I Have changed everything else) but I dont know anything about its internal workings to know if a valve seal goes would it allow air into the system or cause the fluid to just push the abs valves, hence the pedal travel without showing a fault ?
faulty new master cylinder at £280.00 I hope not!!

You should only attempt racing in a LR if your sure your going to win which I have to say is very rarly.
Although I can wind the boy racers up in my 90 2.5N/A because they don't know how to steer, where I STEER round a corner with no brakes (on my side of the road I might add), they come up to them at speed, chicken out and slam on the brakes.
Watching their faces is pricless, and the further away a 17year old landy gets from them the more angry they look!
