Antilock brakes not funtioning properly on "hard" stops
Yes, I never did like ABS brakes because of this. What you have experienced is the ABS system working as it is designed to do. I know, it doesn't seem like you should still be moving after slamming on the brakes, but here is how it works;
When you apply a fast and hard pedal and the ground beneath you is wet the wheels stop at different times. There are sprockets mounted to the rear of the rotors, with magnetic sensors that monitor the wheel info. for all four wheels mounted next to the brake calipers. On a hard stop when the sensor detects one wheel stopping and another still going, these sensors send "pulses" to each wheel until the vehicle has stopped without the brakes having to lock up. The pulsiing is what you experienced and is a normal part of the ABS function.
Please rate this and let me know if it helped.
