Braking issue 53 plate HDI 2.0L

[RossMac]

Hope someone can help, drove put my driveway yesterday and pressed the brake pedal to find it really hard and could hardly stop, after about a minute brakes were fine.
this morning going to work they were fine , but when I came out of work tonight I started the car and pressed the pedal (before moving off) to find it hard again and it took about 15 seconds to soften up.
the only relevant info that I can think to mention is that the fluid level is ok and hasn't moved and I had the front ABS rings done a couple of years ago and no warning lights illuminated on the dashboard.
Any help would be much appreciated.

Thanks

Ross

I'd check for a vacuum leak first..

I don't understand how the vaccum works is that to do with the round servo unit. ?

[RossMac]

is it possible there could be air in the system and its needing bled ?

[trem1]

it'll be the vacuum pump, had this a few years ago on a 407

[RossMac]

is the vacumm pump the block where the break pipes come out of and it has an electrical plug at the front?
