I don’t know if I was clear but I would be making a bracket to adapt the calipers to my 964 and use the 991 rotors aswell.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi I have a 964 and am interested in purchasing some calipers that came off of a 2012 991 c2. The part numbers that I was given for the calipers are 9973524210b for the rears and 997351421/422 for the fronts. I have searched the internet for the piston sizes in the calipers to see if they will work with the existing master. I for some reason cannot find that information. If anyone knows the piston size that would be a huge help. Thanks in advance. Sent from my iPhone using Tapatalk Pro

I don’t know if I was clear but I would be making a bracket to adapt the calipers to my 964 and use the 991 rotors aswell. I just need the caliper piston diameter to know if they will work with my master cylinder. Sent from my iPhone using Tapatalk Pro
