Okay, thanks for the Tip, MTD. I'll keep using that brake grease that
I buy in little tubes then. I find one little tube will do two
calipers/anti-squeal shims. I would hate to go to all that trouble
only to find the pin slides *dry* from seepage or some such.

Yep, upstate NY. Never heard of nasty weather here...;-) Salt? OH you
mean "corrosion accelerator"..


I currently use Permatex Ultra silicone. Seem to work OK but I wondered
if anyone had a better lube. Normally I just flush the bores with
solvent and dry them. Pins get cleaned and burnished or replaced if
pitted. If the seals are intact then I clean the grooves and apply a
thin coat of permatex sealer to hold them secure once installed. I see
the same thing with the aftermarket crap.

If you don't mind me asking, what do you mean by (or how do you go
about) burnishing the pins?

Thanks.

So you couldn't hear in the recording? Did you turn it up loud enough
and listen for the
chittering at the times I mentioned?

Use a fine wire wheel to get any crud off. Then clean the groove real well.
Then the pins get hooked to a mandrel (high tech - cut off bolt that
will thread into them) Then I use what is basically a flat knife steel
to smooth them out. Takes about 30 seconds to do each one. They are
smooth then.

I've been thinking about buying a couple new caliper mounts and seeing
if they can be bushed with a bronze or stainless sleeve.

I see. That's going pretty far but I like your methodology and
perseverance :-)
