I may be mistaken, but I believe Bronco Sports equipped with Copilot 360+ use an electric brake booster (rather than a vacuum booster) and it is integrated with the ABS system. If the thumping only occurs during braking and doesn't change frequency (time between thumps) with vehicle speed then it doesn't seem likely to be associated with the wheel spinning. I would suspect something going on with the ABS, which pulses brake pressure to prevent lockup.I have the copilot 360 +. This noise only occurs when I apply the brakes. Otherwise I don't hear anything.
Normally you would feel a pulsing in the brake pedal when ABS activates, but all my experience has been with vehicles equipped with vacuum brake boosters, which retain a direct mechanical connection between the brake pedal and the hydraulic system actuating the brakes. I don't know if you would feel the pedal pulsing in a vehicle equipped with an electric brake booster. My assumption is that an electric brake booster does not impart any feedback to the pedal because there is no mechanical connection between the pedal and the hydraulic system.
