Hello, my name is***** can be one of two things. It can be caused by a failing brake master cylinder or the ABS module. Most of the time if the issue only occurs under certain maneuvers it is due to the ABS module leaking internally. I usually start by flushing out the braking system with new fluid as most of the time that will allow the seals to close better. If that does not help then the brake master cylinder needs to be leak tested and if it is fine the ABS module may need to be replaced. I hope this helps. If you need anything else please let me know.
