At first, after having to press hard on the brakes while driving in traffic, the brake petal will sink to the floor anytime the vehicle needs to brake afterwards. This would go away after 8 hours or so. Recently, the vehicle does while driving if it goes over a speed bump, pot hole, or sometimes for no reason at all. The petal sinking while braking now last for several days up to weeks. It is extremely dangerous as one doesn't know how much pressure is need to stop at any given time. I have taken it to the shop and nothing has been found to be wrong. Brakes have been bled, rotors and pads changed and the car still does it at random times.
