I just started my PiP after fully charging it, hooked up a small trailer and plugged in the pigtail. Then I moved the car 200 ft along the curb and parked. Realizing that I need to move forward a few more feet, I attempted to start the vehicle, but the brake pedal travels all the way to the floor, I have a traction control error, and the display says I need to depress the brake pedal to start. I've disconnected the trailer pigtail and tried starting a dozen times, with no success.

The brake booster is making noise letting me know it's building up pressure, but the pedal travels to the floor. Brake fluid is right near the max, and nothing has been done to introduce air into the system.

What could be the cause of the braking system failure? I'm hoping to leave in 2 hours, so I'm anxious to get to the bottom of this.
