930 Brake Caliper Part Number Check
Hi,
I did a search and also checked the PET. Can somebody help me with these part numbers? 930-352-541-1R 930-352-541-0R I think that the 1R = Front, and 0R = Rear, but I need confirmation. Thanks!

One of the beauties of the 930 brake is that a right can be converted to a left (or vice versa) just by flipping the outter piston housings....most likely a throwback to the old racing days when spare parts were at a premium...

The original poster had the wrong idea. The numbers he posted are from rear calipers denoted by the 352 portion of the part #. Fronts are 351 part numbers as Steve says. In the third section of the part number the last digit is odd for the Left side and even for the right side (091 & 092). The 541 I'm not too sure about but might be casting numbers for the individual caliper halves.

I am an official knucklehead. I was looking at the first part number that I saw on the calipers, which is the part number that is on the outer half of the caliper. The actual part numbers for the entire caliper is kinda hard to see, it is small and towards the front of the caliper. Thanks for the help.
