caliper kit grease

[parrot]

I have some Seikin caliper rebuild kits which contain two different packets of grease.

One is orange and strikes me as a highly 'refined' grease. The other smaller packet looks like petroleum jelly.

Am I correct in assuming the orange grease is for the piston etc whilst the petroleum jelly like grease is for the slide?

I would say the other way around. Petroleum jelly eats rubber doesn't it?

so thats why you shouldn't use vasolene

i think vaso is pretty rubber friendly.

we use it on rubber o-rings in aircraft engines.

also i would expect it to be dissolved by brake fluid which is why maybe the special grease is for the piston.

might be a simple test: put a little bit of each grease in the fluid.

I know at work, we have to use silicone grease on our o-ringsin our pumps as the petroleum base bearing grease attacks the rubber.

That's pretty much as far as my grease knowledge goes though.

yeah no doubt, but ansell says not to use vasolene with their rubber
