Spongy Brake Pedal

What is your question?

Sometimes the Brake travel is excessive before the car begins to stop. Other times the brake travel is normal. Is there a way to initiate, Automatic Brake Adjustment, when the travel is excessive?

What makes this problem better or worse?

When I pump the brakes it seems to help with brake travel.

How long has your 2015 Buick Enclave had this problem?

Off an on for 2 years.
