911SC - rear caliper ID
Greetings! Getting an 80 back on the road. While going through the brakes, noticed one of the rear calipers has an anti-wobble piston, the other a different piston. Which were standard for 80? They take different seal kits, yes? Thanks!!

How does one post an inline photo? I see the landscape option, dialog window expects http URL... is google drive not a sufficient host for the image?

The caliper on the left in your Google Drive pic has the earlier 69-76 style piston while the one on the right has the later 76-83 cup style piston. Based on the numbers in the two castings both your rear calipers appear to have been replaced at some point with one manufactured in 69 and the other made in 81.

Thanks folks!
Thanks for the quick ID! I assumed the numbers on the calipers were dates, but assuming has its perils. Just getting this back on the road and noticed the rear brakes were not grabbing at all, so time to rebuild. Once extracted and scrubbed up I noticed there were two different calipers. The former owner was a Pcar mechanic, so likely had these on the shelf as spares instead of spending money on new parts.
 Now all we have to do is get the brakes to grab on this:  Thanks for the image tips!! |
