Dielectic grease for electrical contacts and brake pad sliders...? - Grahamm - 25-06-19
Having had a problem with corroded electrical connectors, I'm looking at getting some Dielectric (non-conducting) Grease to put on them to repel water and keep them clean.
I've looked on eBay and Amazon and there's various silicone greases which apparently can also be used on brake slider pins!
Has anyone used this stuff and can comment or recommend?

I used silicone grease on the pivot when I fitted my new brake lever (handlebar). It's compatible with the master cylinder rubber apparently.
I had to buy a tube especially for that, but I expect it'll last me forever

Make up your mind. Do you want it for electrical connectors or what?
For the brake pins, use coper grease.

I've seen comments saying that copperslip doesn't work for the brake pins, but I can't see why!

If you want it for electrical connectors, you need something that does conduct rather than the nonconducting type. That said, get the wrong one for the connectors you are putting it on and it can cause more problems.
Personally, I would clean the connectors up, plug them together and leave them alone. Others would pack vasaline in the back of the connectors to stop air/moisture getting to the pins.

ACF-50 ? for both

ACF50 applied with a small artist type brush

What you're saying about the Vaseline is what Dieletric Grease does. You put it on the connector and the pins wipe it off where they connect.
Using something conductive would just risk getting short circuits.

I might try ACF-50 if I can't find anything else.

If it's for electrical connectors then I use a fibre glass brush for the male connectors and a fine needle file for the female connectors. Once a year and never had an electrical issue. £5 for the brush and £5 for a set of 5 needle files.

The problem was the corrosion was also inside the crimped section.
I'd just like to be able to exclude moisture altogether.

With my job I'd say a shit crimping tool was used without Hellerman sleeving.

See reply#3, second paragraph, by bandit in the recent Caliper pin rounded off thread in the FZS600 section.

I always use a copper ease on the pins.

It was the connectors from the loom to the instruments, see this post: http://foc-u.co.uk/index.php?topic=25376.msg299484#msg299484
There are rubber "plugs" which are, presumably, supposed to stop water getting in and causing corrosion, but they clearly didn't do the job...!
Re: Dielectic grease for electrical contacts and brake pad sliders...? - Salty - 29-06-19
A simple corrosion preventative that I have always used on my bikes is to spray all connectors with WD40 a couple of times per year. I also squirt it into all the handlebar switches. Worked for me so far.

Would a bit of dielectric grease in the spark plug caps and around the spark plugs help prevent arcing to the head from rain water?

I've only ever used a very light smearing of Copper Grease on brake pad pins.
If the bike takes a particularly bad hammering during winter for example then it only takes a few minutes to remove them, clean them up again with wire wool then reapply them with grease again to keep the pads sliding okay to prevent any seizing from happening.
