Can anybody help me with a question I have regarding powder coating brake calipers. Do I need to pull all the rubber gaskets and seals out before baking? Or will they survive in the bake oven. The powder I'm using requires a bake cycle at 425 for about 45min. I figure brake calipers get pretty hot on a regular basis, so i figure all the rubber should be rated for high temps.

 

You need to disassemble and clean them completely. Good time for a rebuild, it's not hard to do at all.
