How is it possible that when we mention the clay based grease to lubricate the Meritor brakes the technicians get a look on their faces like deer in front of headlights?
For goodness sakes who's teaching these techs out there how to be diesel mechanics? What's needed to be certified as a diesel tech, a warm body?
How many units out there have these meritor brakes anyway?
I put small sized plastic cable ties on each of the three grease fittings on each disk brake. I don't cut off the loose end so it acts as a 'flag' to help raise a question to anyone with a chassis grease gun under our motorhome.
In addition to our FT units, Fire trucks are a large user of these brakes, I am no longer involved in the arena of truck brakes. However there are very few disk brakes used on trucks, seems mainly due to lack of understanding on the care and feeding of disk brakes. Know of one outfit that changed all their trailers back to drum brakes after they had problems with the disk setup. Again it went back to lack of care & feeding or mechanics not understanding what was required.
If you down load the Arvin-Meritor Service Manual on the disk brakes and READ it, there should not be an issue for you.
Just posted the Meritor Disk Brake Manual in the Files section.
Ditto on what Dave said about the brake manual.
Basically, you have a grease fitting for your auto slack adjuster, and a fitting on the housing right next to it on the housing grease OK. then you have a vent and another fitting on the housing toward the wheel leave these alone unless you understand the disk system, and have the special grease needed, over/improper greasing here will cause your brakes to drag.
