I have a 2004 Meridian Cat C-7 330HP coach with the Pac Brake. I know with the Pac turned on as soon as I step on the brake peddle the tranny starts downshifting toward 2nd gear, but without touching the brake peddle I can't tell that the Pac Brake is really doing anything toward slowing the coach any.
While coasting down hill can any one with this Pac tell if it does anything by turning it on/off during the decent? I have done this several times and can't detect any slowing motion at all. I do keep the Pac oiled at all the suggested points with regular Pac lubricant a couple times a year and can move the rod in/out during this lubricating so I know it's not frozen up.
My next trip to a Freightliner shop I want to get them to change the downshift point to either 3rd or 4th gear instead of 2nd gear, which seems way to low. Haven't decided yet which gear I want.
