Am currently in the process of rebuilding the Midland booster. There was grease similar to petroleum jelly on a few internal components. What type of grease is this?
Thanks. Didn’t think it was actually petroleum jelly.
I don’t know for sure what was used, but I would use this.
If I can find some silicone dielectric grease locally tomorrow morning then the power brake booster will be assembled using that grease. If it cannot be located then petroleum jelly it is. For future restorations I’ll be sure to get some of this dielectric grease on hand.
