Title: Where do I get clay based grease
Post by: Fred Cook on June 11, 2025, 01:03:21 AM

Where can I get clay based grease for my brakes? I have checked Amazon, eBay, the overall Internet and stores. Can’t seem to find it anywhere.

Frank, thanks for the info. Do you know if it is a clay based grease? And… will it work for disk brakes?

Yes, it is Meritor brand, designed for Meritor brakes. If you have Meritor brakes, this is what you need!

Thought this might help:

Meritor manual states: "Only use Meritor specification O-616-A or O-645 grease inside the disc brake caliper. Do not use lithium-base grease, which can melt from high temperatures inside the caliper. Damage to components can result."

Sirs:
  I have the same concerns as the OP.  I have looked several times over the last couple years for Shell's Gadus U1000-2 or S2 non-melting clay based grease.  Everything I've read says it's been discontinued unless you want a 39 lb. pail.  Checked out the Meritor product mentioned above, but was concerned about the " formulated for drum brakes" while our's are discs and it's specifically for the calipers.  Is the Meritor grease OK?

Phillips 66 has a bentonite based high temp grease called Bentone #2.  Wurth has their SIG 3000 super impact clay based Synthetic good for temps as high as 545 degrees F.  Which is higher than the Shell Gadus.  And you can buy these in a 14 oz. tube.  None of the greases I've looked at mentioned the 0-616A or 0-645 standards.

Has anyone tried any of these? 

A few years ago I took my "new to me" coach to the truck shop here in town and they wanted to use the standard red grease.  I told them not to bother.

Would like to hear what others with these older coaches w/ Meritor disc brakes have been using.

Thanks so much,
Mike Sulley
