I know the title is a bit concerning to read but I installed new rotors and brakes on our 2017 promaster 2500 and when I was on the 4th brake set I found a grease/lube packet in the box. I read I’m supposed to grease the back of every brake and the contact points but never the front. Should I redo every brake or will they be fine. We do have 7000lbs and a full tiny home in the van so the brakes are dealing with a decent amount of weight.
