My 09 lxp sedan with 24k miles seems to have a squeaking/grinding sound when the brakes are cold. Its more noticeable when im pulling out first thing in the morning or when the car has been sitting for awhile and Im pulling out of a parking lot. Once the brakes get warmed up it seems to disapear and it seems to becoming from the front brakes. Does this mean my brake pads need replacing? If this is the case wouldn't they be making this sound everytime the brakes are applied? Also I thought on 8th gen accords the rear pads usually wear out first.
