2006 chevy 3500 express van. 194000 miles, daily driver and tow vehicle.
Problem: Every so often, go to brake and the pedal is rock hard, really hard as in won't move for a split second followed by a split second of, I will call it a "gap" the pedal moves a very small amount to normal pedal and brake feel.
Any ideas before I take it in?
Thanks,
Will
