I have a 2006 Fusion SE I4 I have two issues one is brake fade,i'm fairly certain its the master cylinder. Any thoughts or reference to a TSB would be very helpful. Second is 2 codes referring to the secondary ait injection system( Malfunction). Is it the pump or check valve? Thanks for the help. Eric

It is unclear from other posts on this topic if the secondary air injection system components are covered under the 80K Emission Warranty. Any would be greatly appreciated. I'm at 77500 and have codes po410 and po491. thx
