Must be a east coast/rust belt thing. Dried out pins and rusty contact points are a non-issue out here.
That stuff may be fine on the back of the pads, but it should not be used on any sliding surfaces. It is a rubbery/tacky material.
I know everyone has their favorite brake lubes, but which ones last the longest? I use and like 3m Silicone Paste for slider pins, but what is the best brake pad lube for metal-to-metal contact? I'm looking for something that will lubricate well and prevent noisy brakes, of course, but most importantly, still be there when it's time to remove and replace the brake pads. Any recommendations?
Dow Corning(or is it DuPont now?) has a mass-market line of silicones named Xiameter they sell direct to repackagers and formulators and some of the older Molykote/Dow silicone compounds as well as mass-market silicones not under patent are sold there. I also know Momentive, the former GE Silicones division now owned by KCC of Korea also sells generic silicones for repackaging. I would be surprised if that Mission grease is really a Dow DuPont or Momentive product under the hood.and they have established themselves as a contender to 3M, Dow, Permatex, etc.. Fascinating.
I received the SDS. Based on the NSF number 122830, it appears to be Husky 350 which has low viscosity silicone oil. Husky 220-R is medium viscosity silicone oil and is what they market for automotive brake use. Both are grade 3 grease. Maybe Mission has the wrong SDS? Someone else can pursue this if they choose (I've exhausted my OCD allotment).
Not sure how to post the Mission SDS PDF.
In NYC, you might be taking your wheels off once a year just to see if you blew up a control arm or strut on a pothole, much less to inspect the caliper pins! Seriously, though, the rust is such a pita. I've had stuck caliper pins and rusted hardware causing seized pads more than any human being who drives 6,000 miles a year should be getting.No one is recommending re-doing the slide pin lubrication or metal-to-metal lube to be done every year or two vs having it last many, many years ? Unless the OP changes brakes every 1-2 years ?
Molykote M-77 and AS-880N still have a silicone or PAO base. It’s the solid film lubricants like moly, graphite or fluoroplastics that take over once the oil carrier burns off.Sil-Glyde has similar all encompassing usage verbage. I ignore it.
I think there's a reason both Honda and Toyota FSM's recommend their moly greases for pads and silicone for pins. Silicone decomposes around 450F and brake pads easily get there. The moly powder left behind by the moly grease will continue to work after the first time it cooks.
