I put in an entire new brake system just over a year ago. I use the trailer all the time, in and out of saltwater. I flush the brakes for several minutes every time with fresh water. Recently one of the four drum brakes is locking up. I can usually break it free by rocking back and forth when the boat is on. Usually, but not always, it occurs after it has been sitting for a day or two. Is it time to replace the brakes again?
