That is the problem with a leaking master cylinder – it doesn’t leak on the ground. It leaks into the pedal assembly and doesn’t show up anywhere you normally can see.
With a very slow leak (months-years) the brake fluid causes the pedal assembly plastic bushings to swell and cause the pedal operation to get stiff, most noticeable with the brake pedal ‘return’. This is a good indicator and one reason why I like the OE plastic bushings.
A car that has set or has had the brakes bled by the conventional method, can have a fairly rapid emptying of the reservoir with no indication other than sudden and complete failure. The pedal assembly can hold more fluid than the brake fluid reservoir.
I have had owners complain their 911s kept using fluid and it didn’t seem to go anywhere.
Best,
