Living in Michigan (aka Capital of the Salt Belt, USA) I've had many problems with seized and corroded brake bleeders in the past. As such, any time I open them I like ot make sure they are well soaked in oil before and after bleeding. I also like to leave a little oil in the bleeder itself under the dust cover to inhibit moisture and maybe work its way into the bleeder threads. On the admittedly rare occasion that I need to replace the bleeder, or that I'm installing a new caliper what is the best thread dope to use? There are a ton of options out there so I'll list a few that come to mind but if you have a better choice post it! - regular grease (lb-cg lithium grease, eg JT-6) - #2 grease with moly (eg: schaeffers or Synpower) - white lithium grease - moly compound (eg: Jet-Lube MP-50) - silicone brake or dielectric grease (3M, Motorcraft, etc) - anti seize compound (such as permatex) - thread sealant (eg: Permatex 56521) - teflon tape - oil, of any type - dry I noticed, years ago when installing on a motorcycle, that SpeedBleeders offers a dedicated thread sealant but I have no idea what it is or where to purchase except from them. At this time I typically use silicone brake lube like motorcraft XG-3A or an anti seize compound to prevent future corrosion if its a new assembly but I'd love to go with safest and most effective option out there.
