I am monitoring the brake fluid level at the moment as during the cold period the other week the low level lamp came on.

The level wasn't particularly low but the fluid had been changed on the last service since I last looked. So I am not sure if it was a sticky float on the sensor due to cold weather. But on reading a few threads on here it seems that the fluid can get into the servo.
I have had a look at pictures of servos and I can't see how that can happen as the servo should be sealed. It's a vacuum that operates the master cylinder.

I have checked calipers etc but can't see any leaks. It the master cylinder was leaking I believe it would be seen on drivers carpet.

Brakes are working well and no reoccurrence since. I did top up the resovoir at the time and still monitoring level.

If the master cycling did leak can it get into the servo??
