Perfect, thanks!Minimum 8mm, but 10 is the go-to.

Also, i need some clarification. Are you a GTI fan boy or my boy?Perfect, thanks!
Both... did you ever get the milk you left for?Also, i need some clarification. Are you a GTI fan boy or my boy?
OMG, what did you do?Well, Macan Swap v2 on the R is off to a bad start after about... uh... 45 minutes of delivery of the calipers?
Started to disassemble them. To get the pistons out I use a compressor to push them out as much as possible. But once the first one is all the way out, that doesn't work anymore since it's no longer a closed line. What I did last time, and started doing this time, is taking some electrical tape, putting it over the ends of two screw drivers, and gently pulling them out.
Got the first piston out no problem with just air.
Got the second piston out with the screw drive mentioned above.
Went to get the third out, and the second I applied the tiniest bit of pressure, it started to chip and crumble.

Fuck.
I mean, I barely applied any pressure. Said 'Fuck it', and then just kept trying to get it out.

Whelp, I give up.
So.
1) Any ideas on how to get the pistons out? I can't pry it out using a covered screw driver and the lip. Salvaging the pistons is not a priority at this point.
2) What size are the pistons and/or where can I buy replacements?
Help me, @GTIfan99, you're my only hope!
OMG, what did you do?
Since I was power coating, I completely disassembled the caliper halves.
Anyway, plug up the open holes and use air. Some pieces of shop towel and duct tape.
Where have you guys been able to purchase Castrol RRG in the US? A search shows suppliers outside the US but who will not ship to US. Are other brands of RRG acceptable for use in your experience?

I used to use eBay all the time and now it’s an afterthought. I was able to find some from Bulgaria for like $12 shipped.
Not really... the pistons on the smaller 4 pot are of an inferior metal and the casting is hard, but very brittle... not to the extent, but kinda like tungsten that is extremely strong but if you twist it, it will crack. If you search online there are quite a few instances of people trying to pry out the pistons by the rim and having the same problem. They are design for axial force, not shear force.it's actually a GOOD thing you decided to take it apart.....that thing was begging to fall apart....wow
Ahhhhh ….. I gotcha.
