powder coating procedure question
I'm going to be powder coating my calipers this week. I am familiar with the process, so am fine with that. My question is, is it necessary to disassemble the caliper when I bake them for 25 min at 400°. I'm sure the o-rings are high temp rubber but is 400 pushing it. I would like to avoid disassembling the calipers if possible so let me know what you all think.

I would if it were me. Orings are cheap. I had my calipers powder coated on my Suzuki GSX-R750, and if and when i rebuild them there wont be any chipping when i disassemble them.

Disassemble it.
How do you expect to strip the existing coating? Ensure all the brake fluid is gone so it doesn't ruin the coating during baking? Also as a coater I would never accept the liability of baking a caliper thats assembled. |

Does it make any difference that these are zl1 rotors. The only thing I'm worried about is the possibility off ripping or tearing one of the gaskets or rings. I read that the rebuild kits for these calipers are pricey.

The outer seal is a little difficult to get off and easily damaged but if you gently pry with a jewlers flat blade screwdriver it will come out. You'll see slight indentions on the outer circumference of the seal. That's the best place to pry. Use a little compressed air with a block of wood between the pistons to get the pistons out. The inner seals are square cut O-rings which are easy to remove if you can get behind them, possibly with the same screwdriver. They're a thicker and tougher seal.. about an 1/8", Just don't damage the inner surfaces and you'll be good to go.
