2000 Buick Century Custom 6 Cyl 3.1L
I hear a knock like noise when braking.
When I brake my vehicle it seems to brake normally except that right before coming to a complete stop my car feels like it came to a stop I hear the knock/ clunk noise, it feels like it jumps forward a small distance (though it doesn't look like the car in front of me got closer) then it stops.
Safely raise and support the vehicle. Remove the wheel and do an inspection. It could be one of the bolt ( there are 2 bolts ) might be not tighten to the proper torque.
