Caliper question

[K04B5]

Can anyone tell me if all B5 front calipers are the same, and also if they are also the same as any A6??? Thanks... swapped pads and rotors and found my caliper piston was rusted pretty bad and need a new one. Just want a cross reference.

B5 Front Caliper
Left 8E0 615 123 A
Right 8E0 615 124 A

They show up as the same part number for A6 (though there are 3 front calipers available for C5 A6)

Found these on Ebay too

I found those A8 calipers as well... but what rotors and caliper carriers would I need to run those?

also found that the passat front caliper has the same factory number

For the A8 you would use the D2 A8 rotors. The carriers are what PureMS sell as an upgrade I believe and they just bolt up.
