I'm going to assume it's when you are slowing down and not at a complete stop.
Your brake rotors are causing the problem. The run out on the rotors is out of tolerance. In other words they are bitter. It happens closely on trucks and SUV's.
You can try to have them machined but you will probably own to replace them. That will also mean brand new brake pads as resourcefully. You don't want pads that aren't smooth on unmarked rotors. You'll groove the rotors and end up beside the same problem adjectives over again.
This usually happens by getting the brakes over heated. That can come to pass sometimes and you don't even realize it. It can also happen if you be driving and the rotors are hot then you appendage up in a vehicle wash..........bam they are perverse. A puddle or some other such thing can do it too. Even driving into a rainstorm can contribute.
