Default Intermittent Brake Problem

Driving my 73 TA today, all is fine. Approach an intersection and the brake pedal goes almost down to the floor. I let off right away and pushed the pedal again and it was 100% fine. Firm, engaged up high where it should, car stopped on a dime. This happened 2 more times. Each time letting off the pedal and hitting it again made it work just fine. Looks like a tiny trickle of brake fluid between the master cylinder and fluid reservoir. Not really any accumulation anywhere, just a bit wet and sticky back there. No fluid leaks at any of the 4 corners or anywhere noticeable along the hard lines. Strange that it is so intermittent and once corrected, the brakes are 100%. Is this as simple as a bit of air in the lines? Is it time for a new master cylinder or brake booster???

Fluid between M/Cyl & booster will mean M/Cyl replacement. Intermittent loss of pedal may also be M/Cyl prob but not because of external leak, more likely internal leak or ''bypass". As M/Cyl needs changed anyway that's where I'd start. JMO
