Caliper Lubricant

The book says I need to use PBC Grease when connecting the support bracket assembley to the Caliper. Its supposed to be a meduim grade lube which works at high temps to avoid breakdown and leaking onto the break pads..... Obviously I couldnt find this particular type of grease but I did find something called sil-glyde brake lubricant which is made for all contact point and moving parts.. does anyone know if this is sufficient?
