Brake grease

Reading the forum for the past few years I have anxiety thinking of the brakes, the wrong grease remaking havoc!  So have a few questions
How often should the brakes be greased ?
How would I know if the brakes ever had the wrong grease?
How much grease to use?
Can they be over greased?
The special clay based grease is only for the nipple in the rear of the brake drums?

Brake Shoe Grease A1779W283 Meritor 14.5 oz. Tube - Mibot LLC
Is this the correct brake grease?
It appears to be the same part number
"prflemng recommended 6 years ago"
The price is way less than the $100+ I have found on the web.
Any help would be appreciated

That appears to be the correct clay based grease. It is also available from Mobile SLC32 IIRC. One tube will more than do it . Before you start on your brakes down load an read s copy of the Meritor MM4 brake manual, it will answer all your Questions. The brake calipers are NOT greased as part of chassis service. I do mine every 2 years. The manual is here on the forum. Someone smarter than I will have to tell you how to find it.

Agree. I used the Mobil as well but you must purge the excess grease out and FT has a soft recall on a part you ad that avoids lockup. Get it.

More information or a link or something to identify what your talking about would be nice

He is likely referring to the helper springs. I would guess.

My guess as well, and a very good idea-- Meritor helper spring kit.  Helps keep the "lazy side" of the caliper pads from dragging

Unless he means a relief valve between the 2 grease zerks on the caliper.

You do not have to have clay based grease for the brakes. That's not correct. Meriter recognizes the synthetic as well. It depends on the temperature that the brakes will be operating at. I guess. Find it parts has both the mobile synthetic grease as well as the meritor clay based grease.
I bought three tubes in order to do my brake overhaul, two tubes of the meritor and one of the mobile. Rebuilding the caliper required using almost a whole tube of the meritor Grease..
There are two grease fittings on the brake caliper. Is also an over pressure pop up valve. I believe there's one on the slack adjuster as well. That's per axle.
I bought all new grease fittings to replace the older ones but unfortunately left them in Oklahoma City. So just made sure I clean everything well with brake cleaner before accessing the nipple.
Hope that helps

I've been gritting my teeth and trying to keep my silence but no more.  Sorry.

The high temperature caliper grease is not a "clay based grease."  The Bentonite clay is a thickening agent added to keep the grease from moving too much at high temperatures.

Could be art. But I'm going by what the meritor specs are on the maintenance page that I have. It doesn't the specifically talk about why you would use clay based and I guess what you're saying is correct, don't know for sure. I just know what the chart says. I would think that it had to do with temperature reading this but then again maybe not.

I'm afraid in my world Do What Makes You Field Good doesn't work so I make sure I know what the manufacturer is asking me to do.  Once upon a time wheel bearing grease was heat stabilized with manila rope fiber, fibers from the hemp plant.  Just as fiber greases were replaced by new wonders of chemistry, I'm sure that there's a non-clay stabilized high temperature grease.  I just wanted to point out that Bentonite greases aren't based on Bentonite clay, but are a petroleum grease heat stabilized with high temperature clay.

I guess the picture in post #14 where Meritor refers to "clay base" several places in their literature is the wrong description. And yes after 40+ years in equipment and fleet maintenance and repair I do completely understand the composition of lubrications.
Your description is technically correct, but to us less technical folks it's clay base, lithium base, soap base etc.
