Land rover discovery 3 2005 braking problem

hi, I'm hoping someone can help, we have a discovery 3 2005 and for the last few months have noticed a problem when braking. The brakes work fine at high speed or if used to stop quick, the problem only happens when your foot is depressed on the pedal half way such as going down hill or slowing for a junction. When you are ready to put the brake pedal to the floor to come to a stop, it goes hard and you have to stamp on it to make the car stop, hope that makes sence? I have phoned land rover, our vehicle was part of a recall for the p017 fault on the vac pump pipe, cylinder head and the servo and had the recall work done in 2011 but have been told only the pipes were replaced. Does anyone know what could possibly be wrong, we go on holiday soon with a caravan on the back which is not good with no brakes! so need to find out what it is as soon as possible, hope someone can help, thanks in advance, Amy.

When the p017 was done they would of checked to see if any engine oil had found it's way into the servo, if it had a new servo would of been fitted and possibly a new master cylinder if that was contaminated. I have seen vehicles that have had the P017 done but failed again. Remove the vac pipe from the servo and use a tywrap to dip the servo to check for oil. if it has oil in the servo a new servo will be needed. Also while the pipe is out put your finger over the end and start the engine, you should get vacuum which should hold when the engine is turned off, if not or there is oil comming up the pipe the pump will need attention.
