25 years, 150,000+ miles driven, all brake pads are original. One day, when in MOT shop where we could hang out with tech, saw one side brake pad looked worn and asked pads to be replaced.

Parts department sent out new pads and I had the surprise to note that one side of the new pads had less thickness than the other and that both the original worn pads and the new pads measured about the same. So, the new pads went back to Parts and we did not change brake pads.

Probably with cleaning, replacing few pitted brake slide pins, lubing slide pins with Corrosion X, then wiping it dry, and using transmission retarder kept the brake pads from wearing very much. Regular proper lubrication & purging caliper helps, and rotors are also looking good and original. We always had a thin black cable tie around each of the brake zerk grease fitting to help that they are never accidently greased by any tech that may be greasing front suspension.

We later added brake springs.

Barry you can see the difference in the thickness in the photo I posted. The previous owner had the dragging brakes. The replacement new pads other than the worn out one were the same thickness as the replacement. Thin on inside thick on outside. There is a vibration dampener on the outside of the pads and mine were all damaged when I replaced the other three also. I carry the one good pad incase someone on the road needs it. Would easily get you home. The outside pads are both thicker and smaller in area of the pad. I'm sure you could also cut down the pad on the mill for other emergency spares

I wish there was a video of this. Maybe we can make one, I'll do the work, stop by and show me how :-)

If the corrosion X seeps in where you can't see the pin,great but why wipe it off,we have been using the dry teflon spray for years,no problems,and if you grease the coach yourself you don't need the ties.

I hope it's not to late to respond to this but I would like to be more clear on this zerk that doesn't need greased. Are you saying it's a zerk for the slide pins and needs a different grease? Is the grease Corrosion X? Or are you lubing the pins with dry Teflon spray ?

MM,

1. No. The that is being talked about is for the area in the caliper that has the gears that moves the caliper.
2. either will work for the pins
In the media section there are a couple of copies of the 4m brake book that has a better explanation with diagrams. I will post a link later (Unless as someone beats me to it) as I have to run.

Here you go, The selected media item is not currently available.

Lubing the pins with the dry slide,to me the x will collect dust etc.,the zerk on the caliper is for the clay based grease,as said
before if your lubing yourself why put a zip tie on it?

Springs can be bought for half the price some places in Texas charge. I bought mine thru Freightliner truck parts for exactly 1/2 the price.
