Thank you ... yes it repeats but I generally ease off the pedal when it starts so not entirely sure how long it would last ... will try and post something this evening or tomorrow morning.

Thank you again for the input ... thinking through this ...
ABS ... (basics)
1. Brake pedal is pushed
2. Wheel sensors detect skidding or 'locking'
3. ABS pumps (releasing the brakes) the brakes by pulsing fluid flow to the brakes.
Pumping the brakes might be triggering the ABS module into thinking that a skidding event is taking place or the sensor is misreading the pumping of the brakes as a 'locked' condition.
Researching to see if there is a way to monitor the sensor output as that would help in determining where, if there is an ABS issue, the issue might be.

Have you checked for stored trouble codes?

Agree ... not the only nor the first ... Correct, the difference in the wheel speed between the wheels. No Slip light and no stored codes.
Thank you for responding. Will have more input later this evening.
