Now that I think about it, what you are probably feeling is the "Brake Energy Regeneration system" (BER) kicking in when applying light pressure to the brake pedal or coasting in certain situations. The BER is actually the alternator engaging to charge the battery, putting an extra load on the engine causing engine braking, which slows the vehicle by slowing the wheels making it
appear as though the system is applying extra brake forces.
