You'll probably need to get a vacuum gauge and check.
460cixy checked and tested a pump for me last week just so I knew what vacuum to look for on mine and it surprised us both by pulling 24" at idle.
Also have a really good look around the booster where the m/c bolts on, and with the engine running listen for any hisses.
Get someone to jump on the brake pedal HARD and look for deflection where the m/c bolts on at the booster.
This will indicate a crack too.

One of the members here posted a video of a cheap one he bought and the flex at the M/C had to be seen to be believed.

Great thanks for the advice. I have ordered one from British Offroad.

Just to bring the thread to completion - I put in the new servo and braking is 100times better. Thanks all
