Not all of them. Mine do not.

Tried that. Doesn't work if the pads are bad.

Cool. But that can looks like it's kinda old.

Sure it's "new" government surplus, but the government got rid of it for a
reason...

That stuff is harder than HELL to find, and doesn't seem to be sold in the
US!

Guess I'll stick to my off the rack AutoZone brake grease!

It is. Click he

Click on "Find a Distributor" and choose your state.

I'm gonna bite the bullet and buy the $66 2.5oz tube. I feel the same
sort of awe I felt when I bought my first genuine Snap-On wrench:
Wowwwww...the REAL thing...

I tried and failed to take descriptive photos of my rear discs, whose
friction surfaces resemble the dark gray coating worn by a rifle barrel.

The fronts had patchy glaze, where the outline of the pads was imprinted
over and over again in an irregular pattern around the disc, some lighter,
some heavier.

I had some serious front brake vibration. A check with a dial gauge showed
the discs to be dead true, and yet I had a high-speed vibration. The only
conclusion I can come to at this point (surely to be opposed by some
others...) is that the glaze caused sufficient frictional differences as to
cause steering wheel wobble ("vibration").

What components do you put the anti-seize on? I only put this on the
two caliper bolts. For the shims of the brake pads I only use the
Molykote which is supplied with the OEM pads. I have yet to have this
happen on my rotors and they have 116k miles on them.

be in no doubt, if you have that kind of surface contamination, that can
/definitely/ cause vibration.

for brake rubbers, according to this link
http://www.dowcorning.com/content/au...otive& DCWSS=
molykote 33 can be used for brake rubbers. which is just as well since
i've used it may times in the past!

anyway, the point is that it's relatively readily available and
relatively affordable for the true silicone brake grease addicts.
