Anti Sieze

During a conversation with some other owners recently the subject of slide pin lubrication on our Meritor Disc brakes came up.
It was stated that anti seize could be used on the slide pins to prevent calipers from failing to return.
I do not recall any thing from the Meritor Manuals that says anything about lubrication of the slide pins.
I would think that as thick as anti seize is that it could hinder the free movement of the pins.
Any experience with this ?

Gary, I have used anti seize for many years at work but mainly on nuts and bolts and some parts I didn't want to stick together. Don't think I'd use it for what you are talking about.

Gary,

Went and pulled my brake book and on page 42 #6  states NO ANTI-SEIZE. In big letters too. Don't know about all models but that's for ours.

Gary,

http://www.foreforums.com/index.php?action=media;sa=item;in=1701 Look on page 47 of this book that Dave M posted and it is the same as ours. Mike said that as important as the brakes are this is one thing that reading the instructions first is a must. (along with 2 or 3 times as you go)

My guess is the anti-seize attracts dirt, grim and sand that could ultimately cause binding.

If you look at the brake pins you will see they have a fairly hard chrome plating on them, and the calipers have bushings in them. Even when everything is new they fit together rather loosely, as others have said I would imagine all never seize would do is trap dirt and dust and bind things up, or cause excessive ware.

Gary,
  I noted this before when posting on the helper spring addition, on page 40 of the brake manual linked above under the "reline the brakes" topic it says
"18. Clean, inspect and measure the slide pins and bushings. Refer
to Section 12 for information about cleaning the brake
components.
A. Clean the slide pin. Remove any paint or other material
from the pin. Replace the pin when you find burrs, nicks,
corrosion, or other damage. Lubricate the slide pins lightly
with WD-40, Spray CRC or a similar product."

I would not use WD-40 as it is not a dry lube and it will attract dirt etc. I used one of the silicone spray lubes that leaves a dry coating. WD-40 if left alone will dry and leave a gummy residue. And note that the lubricating noted is done after cleaning the slide pins.
Good luck,
Rick

Rick,

Some type of dry lube is what we have used for this application. Our storeroom always stocked LPS products (we just used WD-40 as a starting fluid on some used up old power units). As has been touched on, anything as heavy as an anti-seize like Fel-Pro C-5a would only attract any road grime and clog the works. Another thing to touch on is some people think if a little will do a little good then a lot will do a lot of good. This a good case where less is way better than more.

Thanks guys, Y'all are confirming what I thought. I have used a dry silicone spray in the past with good results.  I thought that the speaker about this subject was a great authority and before I said anything about it I wanted confirmation.
Thanks

Yes,

Only dry lube products on caliper pins.  Because of the location anything else will turn into a grinding compound pretty quickly.
