Yes, correct

This symptom rather points towards a faulty servo. Disconnect the line that
goes from the servo to the reservoir and start the engine. If the servo is
OK, you shouldn't get more that a few drops from the line.

Weird. Normally the brake light you are referring to is activated only by
the parking brake. Low brake fluid level, low hydraulic fluid level and low
hydraulic pressure are signaled with auto check light. See if the pressure
switch on the brake servo is connected.
