I use the same silicone base brake lub that I use on my car. Autozone, etc. carries it.

What does it do? Prevent anything?

Default Lube

I think it helps to lube the pins so they slide smoothly and between the pad plate and puck, it is sticky and seems to help the parts keep from vibrating. At least that is my thoughts and it has worked well for me, so I keep doing it. Others may say it's not needed. To each their own. My brakes work great and don't make noise.

Default Brake Caliper Pins

For the record, in 14 years I have never used lube when changing brake liners and have never had an issue with the caliper alignment. Probably doesn't hurt as long as you don't get it near the liners.

I'm pretty sure a thin film will help reduce/prevent corrosion.

I've not done mine yet (still in the packaging) but I had assumed there would be dust seals on the pins.

If there are no dust seals then the downside will be dust/grit sticking to the lube and causing extra wear (especially when using grass runways).

Here in the uk it is probably still preferable to leaving them open to the moisture as I think the extra wear would probably be less problem than the corrosion.

I'll have to check with my inspector to see if my thinking is correct.

I use the dry graphite rattle can spray on them. It drys and doesn't pick up dirt.

A slightly different setup, my Sky Arrow has Marc Ignegno brakes where the caliper is fixed and the rotor floats on pins.

I had one brake dragging, and it was due to corrosion on the pins causing them to bind:



This can also lead to uneven brake wear.

It's now my habit to very lightly apply disc brake lube on the pins with a q-tip, more or less monthly.

In short, I think a tiny bit of lube on any brake part that's designed to slide is a good idea.
