hey guys, i am gettin a whining noise from my front end while i am driving periodically. my friend had a 97 maxima and it was coming from his car and he had to replace the rotors/calipers. but as i was talkin to him the other day, he said that he didnt need to replace, that the caliper was sticking to the rotor. and just needed to be spaced or something like that. when i brake the whining noise goes down. any help on where to go is appreciated.
