2009 GMC Acadia SLT 6 Cyl 11.1L

Brakes

Spongy brakes occur when gently decelerating.

The car has 54,000 miles on it. Problem began about two weeks ago. Brake fluid is full. I must sometimes pump the brake twice or more to get it to respond.

Air in the brake system can make your brake pedal feel spongy and vague.
