On my moms 2000 XJ Sport we've been having a pequliar problem lately. When starting to drive after its been parked for any perdiod of time, there's a really loud squeak that comes from the front end. It will stop if the brake is gently applied and goes away on its own after about 50 yards. Her ABS light has been on for about 3 years, but still works. It happens less often and on a lesser volume after we power wash the front end. Any help would be appreciated. I can try to get a video soon

 

rotors has surface rust on it.
