Otherwise you can cause the plunger to skew itself and then you don't get full travel on the pedal and screw up your servo and the center pin on the servo can pop loose of the fingers holding it to the diaphragm.

Then I changed the vacuum pump model to a later version (no diaphragm) and still wasn't resolved. Tested the vacuum and was working perfectly - so moved on to brake servo.
After failing to find a new mk1 servo, I opted to call in to Crazy Quiffs for a new MK2 brake servo / master cylinder who then fitted it - but still not fully resolved.
Full front upgrade to Mk1 GTI callipers and discs, with lots of trial and error later - it was resolved. Never fully understood the root cause, but changing EVERYTHING for new did solve it, and other than the cost of wasting the first set of discs/pads by upgrading, has left me with an infinitely superior driving and stopping experience! I would recommend.
My car is 1.6D so some differences with how the vacuum creates suction off the engine if yours is a petrol engine, but all in all quite similar.
