I'm in the middle of breaking down my calipers to have them powder coated
by a local shop, but have some questions for someone (anyone!) who's
done this before.

I know that all of the rubber gaskets, etc. have to come off before the
calipers are baked during the p-c process. So from what I can tell, I have
to dissassemble entirely the front and rears calipers, right?

Regarding the rear calipers: The schematic in the manual indicates that there
is a rubber cam boot within the e-brake assembly that must be replaced, but
I don't know to remove the cam itself Also, there is a rubber cup and an o-ring
behind the spring cover but I'm not sure how I remove the circlip and the spring
cover so that I can get to these last rubber parts. [I have already removed the
rear pistons].

Can anyone tell me how to proceed?

Thanks!
