Ordered a 914-6 rebuild kit from Pelican and when I was ready to install the dust seals, they were too tight, and the sealing rings were too small. Someone accidentally sent me a 914-4 rear caliper rebuild kit by mistake. My calipers are complete except for installing the pistons. Can someone please school me as to what size the pistons are in the rear calipers, and what to order. Are they the same size as A or M 911 calipers? Be easy to just order the rebuild kit for a pair of those. Thanks!

Give Eric at PMB Performance a call. He will get you dialed in.

Just did the front on my 6. Had the same problem with Pelican. Got Centric parts off eBay from oempartstitan. they worked perfect.

914-6 as well as 911 M rear piston size 38mm up to '83
914-6 as well as 911 A, M, S front piston size 48mm

914 rear piston size 33mm
914 front piston size 42mm

Speedo, send me your shipping info. I can send you a set for free.

THANKS FOR YELLING... I fixed it.

Thanks PM sent.

Sorry, I did not mean to yell, just to make it stand out as a reply, not the original.

No worries Dave I was just I didn't proof read before posting. thanks for the correction

Ok you two, take it outside

Going forward if I don't want to do a complete caliper rebuild...what do i order to get the M caliper 38mm rebuild kit with the sealing ring, dust cover and metal retaining clip?
Just an M caliper rebuild kit? PP and SM require a year and model car.
