Q: Pulsating brakes.

Hello. All of the things that you listed could potentially cause the pedal to pulsate. If a wheel hub was recently replaced then I would move on to looking at the other hubs, as well as the rotors and pads. It may be possible that a different wheel hub is the source of the issue. A check for bearing looseness would determine if this is the case. Worn brakes and rotors are another very common cause of brake pedal pulsation. If the rotors go out of round, or the pads wear unevenly, they can cause the brakes to pulsate when pressed, and in more severe cases to pulsate any time the vehicle is moving. A disassembly and inspection of the brakes could determine if this is the issue. A fault within the ABS system is another possible cause, however less likely if the ABS light is not on. Also keep in mind that a bit of pedal pulsation will be felt whenever the ABS system kicks on, and could be considered normal under heavy braking situations. I would recommend having a professional technician, such as one from YourMechanic, come to your location to diagnose the cause of your pulsating brakes.
