Doing my own brakes (97 Accord) - need some advice

How does one "pre-read" something?

You either read it or you don't!

Yes, it's sort of a kind of lubricant.

Another example of that sort of macrolubrication is bentonite grease,
which is made with a kind of clay that has big flat pieces that slide
easily across one another.

I tend to suspect silicone dielectric grease is more effective on
connectors, but the lithium grease is cheaper and should last twenty or
thirty years.

You'd be amazed how many people say, "You do your own brakes?!

Um, yeah.

 

It has been my impression that galling was a phenomenon most commonly
experienced between metals that were close in hardness. In other words, if
one metal was significantly softer than the other, galling wouldn't occur
for the reason that the softer metal would simply smear instead of balling
up.

And simple surface-texture embedment. From what I've been told by an
engineer at BoltScience, embedment is the primary reason that loosening
torque can be several times what's applied while tightening.

Oils are not compatible with water. If oil is present, water cannot
generally react with the metal. I have found that just about any kind of
oily substance will keep rust off the threads, provided it does not wash
away.

I have found (after a lifetime of living in the Rust Belt) that rust rarely
penetrates more than one turn of thread. It's corrosion of the head to its
mating surface that makes such bolts hard to remove. If the bolt goes into
a through hole, the end thread of the bolt will seize at its bottom turn,
which is why these often need to be drilled out.

I wonder why my car has absolutely no substances applied to any of its
fasteners that go into aluminum holes? I guess the bolt itself may have a
plating or wash that consists of an anti-seize?
Toyota's OEM spark plugs that were intended for 100K mile intervals used to
be cadmium plated, to prevent seizure. I'm told they've replaced the
cadmium with something else that's supposed to be more "environment
friendly".

 

The most flagrant example of galling, (in my experience), was with large
stainless steel bolts/nuts in the semiconductor equipment mfg biz.

Since such assembly operations took place in clean room conditions, use
of grease, oil etc. was not an option. In fact, the only possibility wa
the use of IPA, (isopropanol), which worked to reach the required torque
spec...

it is - it's oem. bearing grease isn't a good insulator, is not good in
the wet and can deteriorate the plastic materials used in the connectors

it's not the grease that matters - it's the connectors!
