We have 4 Rockwell Meritor calipers on our bus and I just finished a complete overhaul of all 4 including new chambers. You have the current slide pins which are the upgraded version from the original pins which used O-rings. Rockwell did however add a additional single string that goes on the top pin only to help return the caliper. I'm not familiar with that spring that goes between the pins. To me this doesn't seen to serve any purpose at all.
