im going to powdercoat my brembos soon, and i was wondering if i have to disassemble them when i do. i was going to remove the bleeders and lines of course but do i have to pop out the pistons when i bake them? the powder i was looking at using recommended cooking at 350-400 for 20 mins.

any help is appreciated

 

Yes. The rubber sleeves will melt if you don't.
