?? I think Bushie was trying to get more data to point you in the right direction.
Is the brake pedal soft and spongy with poor brake retardation when pushed, or it it rock hard with poor retardation ? Does the pedal pump up hard without the motor running ( no vacuum assistance ) or does it stay soft ?
If you can get a set of brake clamps and clamp all the lines off, it is a good start. If your pedal is suddenly nice and hard, the booster is probably ok. Let each clamp off in turn. A change in the pedal feel could indicate a potential problem at that wheel.

A process of elimination.

What I found with a cracked servo is that you don't necessarily realise that pedal force has increased over what it was like in the past.

It only really triggered for me that it was a servo issue when the pedal went rock hard and I couldn't pull her up one day.
The interesting thing for me was that I realised this had been happening over many, many months of driving but only getting worse incrementally.

new booster fitted today.........have brakes back now
