Is this normal?

On my 2015 Jeep Grand Cherokee if I'm idling and press the brake pedal a few times the brake pedal becomes still as if the engine was off but once I start moving its ok again. Is this some kind of feature? Thanks

Our 2015 Altitude does the same thing, I think it may be using up available vacuum while idling because of a check valve. This is just my theory of mine because I don't believe anything is malfunctioning.

Yeah I don't think anything is wrong with it, have the same jeep as you do, the altitude. Appreciate the feedback. Was curious.

Yes it is normal. You're pressurizing the brake system. The master cylinder is sending pressure to the calipers via the brake fluid. There's a vacuum line off the master cylinder that runs to somewhere in the engine.
