Reply to "vacuum assisted brakes"

panteradougMember

Typically the rubber components in these assemblies do not like petroleum based substances. They tend to swell the rubber and do not lend to lubrication properties at all.

You want to keep petroleum based fluids away from the diaphram as well as brake fluids.

The boosters do not need lubrication.

They have internal components that are made from naturally slick materials.

So the answer is no, it is not a good idea. If they are holding a vacuum, leave them alone.
