When I hit the brake the car starts to vibrate severely, almost feels like the car is going to fall apart. I don’t think it’s the brakes but could be. and when I hit the brakes the pedal goes in and out like a pumping action. and when I'm just driving there is NO vibration what so ever. Please help I cant even drive my car like this.
