when I apply the brakes
Since the ABS light is on, it very well might be the ABS kicking in when it shouldn't or your brake rotors/pads are old. Might be a wheels sensor, or more. A safety issue for sure. You will need to have a mechanic scan the car for the codes, (ABS light on means there is a code stored) and will be able to tell what the problem is and repair.
