Default Brake Paddle Bounces Back.

I am experiencing this lately as I apply the brake the brake paddle bounces back under my feet. I am wondering if it's air bubbles in the brake line or something else.

Sounds like the ABS wheel speed sensors are out of adjustment or malfunctioning in some manner.

Concur, this can be a major safety issue. Have it looked at sooner than later.

Called the maint shop & they asked if I see any warning sign on the dash but I don't see no ABS warning. I will take the car in tomorrow.

You mean pedal pulsation?

Possible the rotors have run out problem.
