First, I know Pizzaguy will chastise me as I store my XF in the winter and only start it once a month and drive occasionally on a nice winter day. I had my state inspection done last fall at the dealership where I purchased my XF (as there is no charge) and had them replace/flush the brake fluid. Brakes were mushy before this, had to pump a second time to get the pedal up. I did not drive much the rest of the year but before storing for the winter the brake pedal again needed to be pumped a second time to feel comfortable stopping. I went for a spin last week and now have to pump the pedal several times to brake. I tested the master cylinder with the car off and had a stiff pedal on the second push. I took my foot off the brake and pushed again, and the pedal was solid almost immediately. Any ideas what may be causing this "no" brakes issue. BTW, this is not my daily driver and only has 29k miles. Thanks in advance.
