So yeah... new to the forum, not new to nissans. Owned a previous S13 back in 2001-2006.

So this is what I did today.....

Disassembled the calipers to get them ready for powdercoating.

Started taking pics a few moments after starting.
Image

I had a piece of drywall, which actually worked better due to me being able to just break off pieces in whatever size I need
Image

Another pic...
Image

Two more pistons out...
Image

Suckers are stuck...
Image

Got half of them out so far...
Image

Stuck again...
Image

It was a recurring theme, they would start to come out but stop at a certain point. At one point I was pumping 70 to 80 psi at them to try and shoot them suckers out. Started to get real frustrating. I tried grabbing them with pliers and a towel and just couldn't get them out.
Image

I was pluggin one hole with my finger (hehe) and as hard as I could shoved that sucker in the other hole (giggity) but can anyone tell from the picture why I was still unsuccessful? (I am not proud as it was a dumb, simple mistake)
Image

Slowly working more pistons out one by one
Image

Break time. Frustrated at this point because some are still stuck. Time to get creative but first...
Image

Adenosine Triphosphates intake
Image

Tried a c-clamp with plastic covering one of the holes to get a secure seal, still failed...
Image

Did anyone guess it from the earlier pic?... I had the short section of hard brake line still attached and open. So I twisted it shut and BAM!!! Please do be careful if you've never done this, these suckers FLY out, especially since I had the calipers split apart already they were shooting out 10 plus feet
Image

This sucker was stuck so I c-clamped one piston to stop it from flying out and c-clamped one hole shut with plastic covering for a sure seal. Success!!!!!
Image

Finally got them all out. It took awhile as you can see they are in bad shape but not gone.
Image

After alot of working at it and pure persistance, finally done!!!
Image

If anyone wants the rear Z32 caliper brackets for free, you pay shipping, just hit me up
Image

It took longer than I thought so I couldn't drop them off to get powdercoated today, but here they are all ready to go come Tuesday morning!!!
Image

Thanks for stopping by and I will put up more pics as it gets further along!
