I'm planning on powder coating, and rebuilding my calipers.

[muzzymaniac]

I'm going to attempt to rebuild a caliper tomorrow. This is going to be my first time. It looks pretty straight forward - does anyone have any tips? Maybe point me to some good threads or links?
Do I need to grease anything or will brake fluid suffice?

Thanks!!

Use only brake fluid, you don't want to contaminate brake fluid with oils, greases or solvents

Muzzy, why even bother?

I didn't even know you could still get the parts to rebuild calipers anymore.

They're so cheap to begin with, it wouldn't be worth it to me.

By the way, I don't mean to sound condescending...

Where did you find a caliper rebuild kit?

Advance Auto had them. I really don't need to rebuild them I plan on powder coating them and originally planned on rebuilding them. After some thought I may just mask and plug the crap out of them and leave the pistons alone. It's only going to be about 375 degrees. I think they should be able to handle that.

I would suggest that you ask JTSmith this question. He's the expert on powder coating. I could add this to the title to catch his attention for you.

They will be fine as is. The seals are silicone.

Just get them very clean first.

Jon, I read one post in your other thread that it's possible to powder coat plastic (or was it wood). I think you have your oven on 400 degrees. Is the trick to it based on how long it's being baked? I guess anything could get damaged if it's exposed to extreme heat for a prolonged period of time.

What is the boiling tem of brake fluid?
ever seen a rotor get cherry red hot?

The temps needed to powdercoat a caliper are well within it's operating limits.

Oh-
Be sure to mask the square area where the banjo fitting screws on-not just the threads-
you can just cap off the bleeder valve with a silicone cap

Mask the areas where the pads slide on them also

There is a picture in the Haynes manual showing how they test twin piston Corvette calipers. It's looks like a welding machine blowing up fire works. Sparks are flying everywhere. I'm sure that temperature could never be reached under normal situations unless you're a race car driver.

Thanks for the title change BB. Thanks to Jon for the info too. I'll let you know how they turn out.
