Getting running again

Hi everyone.

After years of just letting her sit, I got my wife's 67 Newport 2dr running again.

A new battery and a clean up of the carb and she took off.

You could hear the lifters begging for oil at first but after 10 min at idle she is purring beautifully.

I have no brake pedal pressure (even after topping off the master cylinder) so I'm sure there is a leak.

Whats the best place to start looking for the brake leak?

Thanks
