3406E weak jakes

On my 3406E when the oil is cool first thing in the morning the jakes pull down hard, but once the oil warms up to operating temp they get really weak, lash is set to factory spec, thinking they prob need to be rebuilt what are your thoughts on this? It's in 2001 Pete, motor is actually from a 99 freight liner, ESN is 2ws09524 and they are a pacbrake not 100% sure on which model, thanks guys!
