77/78 rear El D caliper HELP, please
 

Hello. I have a question on El Dorado calipers. My truck has a rear disc conversion that uses the caliper from a 77' or 78' El Dorado. It was a 4 wheel disc, hydroboost setup. I have tried as best as I can to google my problem but have had no luck. I tried a search hear also. Forgive me if I missed the answer somewhere else on this site.

I am looking for a diagram, and perhaps instructions on how to "wind back" the pistons. I have never encountered this before. I also have a torn dust boot that I would like to replace. I guess I want to tear them down. I do not know how the parking mechanism works. I also think the calipers are not working properly. I do not currently use the parking brake mechanism. (no cable attached). I have a manual line loc setup at the moment. Would the caliper still set itself or do I need to make some adjustments? It's all new to me.

I thank you all in advance for any info.


Good luck with ALL our rides.
