    What seems kind of normal to me is once when you open the driver's door after sitting for a while, and once every few uses of the brake. How many a 'few' is depends on several variables including how hard you apply the brakes.

    What you don't want is for it to sit there repeatedly pumping for its own private reasons when you're not even applying the brakes.
