Hello folks

2005 Dispatch, 1.9d (non-turbo) - DW8B I believe?

I have an odd issue, as above - the brakes are only assisted for one quick use of the brakes, then the pedal goes hard. Oddly it's worse with a light application of the brakes - a hard application results in some decent brake force for a longer period (briefly!)

Vacuum assistance soon returns when you come off the brakes and give it some revs, but then gone again just as quickly the next time you use them.

I've only just bought the van and there appears to be fairly new vaccum pump (which I've had off and checked - fresh seals, new pipework, unworn cam pegs). 

What should I be looking at next? Servo?
