How to Lubricate a Drum Adjuster

Video Transcript

Hi, my name is Nate McCullough. On behalf of Expert Village, in these clips, we're going to talk about the proper way to inspect and adjust your drum style rear brakes. In this clip, we're going to talk about the proper way to disassemble, clean, and lubricate your brake adjusting screw and star wheel. Now that we've let our solvent sit for a while on our components, you can go ahead and take and dry them off with a shop rag. The reason why you're going to dry them off with a rag is that, if you're like me or you, most of us don't have an air compressor that we can air dry them with. You're going to want to stick you're rag down inside and make sure you clean all the goo out from there. Set this component down and move on to the next one. It's going to be opposing receiver cup. Dry off the outside of it. The solvent is not good for you brake shoes. If you leave some dripping on it and reinstall your adjuster, it is eventually going to find its way onto your braking surface. You don't want that to happen. It will mess up what they call the co-efficient of friction which is the gripping force between your brake shoes and the brake drums. See all the goo that came out of there. We'll set this one down and move onto our star wheel adjuster screw assembly. See if you can get the threads real good. You don't wan to wire wheel your threads. If you have a brass brush, you can put the brass brush to it. You don't want to put it to a steel wire wheel or like a bench grinder wheel. It will tear the threads up a little bit and monkey up the way that they work together. Nice and clean...and we have our thrust washer we're going to clean up right there. Once you have all your components dried, you can move on to lubricating them. When it comes to re-assembly and lubrication of your adjuster assembly you can use a silicone derived lubricant or anti-seize. You are not going to want to use W-D 40 or wheel bearing grease, or anything that is petroleum based. Petroleum does not break down the way it should. And if it gets on your shoes it will lubricate them and cause your brakes to lose almost all of their stopping power. What I have here is heavy duty silicone spray. We're going to give the threads a shot just like so. We're going to spray the end of our receiver, just like so and set this one aside. We're going to give our receiver cup a good shot...and the other receiver cup a good shot. That's the lubrication process. What we're going to do now is assemble our adjuster. The thrust washer goes on this side. The receiver cup with no threads on the non-threaded side, and the threaded receiver cup on the threaded side. We're going to screw it together. You're going to want to pay attention, before you dis-assemble your adjuster wheel, to the approximate location to where it was before you took it apart. What that will do is save you excessive adjusting time once you have the system re-assembled. That is the proper way to clean, inspect, and lubricate your adjuster.
