Brake Fluid for Cleaning Bolts?

Yes, that's precisely it.

Thanks. But on this one, I am not inclined to experiment. It
just seemed like people would do it a lot, or they never do
it. In which case I don't want to be the guinea pig.

 

They did make my hands sweat. ;-)

I had a hard time with one of the plastic "bench bleed" connectors;it would
not thread into the MC. (nor the old MC)

Murphy's Law struck again.(it happens every time I work on my car)

 

The real question is why? What are you trying to do by soaking the bolts
in brake fluid?

do you have paint on the bolts that you want to remove?

Regular motor oil is a better lubricant.

What were you planning on doing with the fluid after you soaked the
bolts in it?


Makes no sense.

Time for my 0.02 ...

Yes, water absorption IS the problem, as this causes the normally inert
fluid to become contaminated with acidic compounds. Leaving a residue of
brake fluid will cause rust to start in double quick time as the acidic
compounds expose raw iron to oxygen. If you doubt this, look what happens
to, say, a cast iron clutch slave cylinder that leaks: it gets covered with
a layer of rust.

Much better to replace a rusty bolt with a new one, and use an anti-sieze
compound. If you must wipe bolts with something, use WD40 or engine oil.
