this is for the rear caliper on the UrS4 and S6...maybe others, too

Oops, one more thing. The seal for the rear caliper parking brake cam
mechanism / shaft is an oil seal and not an o-ring. If anyone is rebuilding their rear calipers, I have spare seals. I can also provide
dimensions and / or a Chicago Rawhide part number.

Chicago Rawhide 6405 16x24x7 it is a little taller then the stock piece, but has worked flawlessly.

>Is this OK or did the rebuilder forget to put one in?
