S4 front caliper question

[87S4]

Hi all. Im a new 928 owner and Im quite familiar with 944s so im not totally Porsche retarded....so here's what I need some help with or clarifying.

I need new front calipers,rotors and pads. The calipers are whats giving me trouble sourcing(im in Canada), looking through pelicans part list they have 2 different rebuild kits, a 36mm and 42mm I believe, no rebuilt or new calipers available...
Does anyone know of a place that has rebuilt or new? Should I get a rebuild kit and have someone rebuild them? Is this rocket science? Sorry but I am brake retarded. Just looking for input on the best route to take...I may take a good set of used if anyone has a set. Thanks for your time

I have sourced a company called Goldline in Seattle, Its 8pm and the fellow answered the phone and talked to me like it was 10am on a working day, I read some of his feedback from past customers...Im sold with 41 years in business

what do you want to do??
If you have a set of S4 calipers simply put a piece of wood tween the pistons and with some compressed air about 15psi should do, pop out the pistons without damage to the sides,
use a razorblade on the piston sidewalls held perpendicular, scrape off the old chad,
with a wood toothpick remove the inner seals clean out the groove use some silicone paste on the old seals and put them back in and your done.
.......Dont try to remove the outer piston covers they can stay in place.
