I took mu 39 in today to a mechanic who does brakes,, I knew I would not find a guy who has done this type of brake system I have ,

He did well ,,he bled my lines for me ,,he found that the bolt holding the wheel cylinder onto the backing plate was the culprit that was wearing a groove in my drums

He took a peanut grinder and took off 1/8 inch and it stopped the grinding noise both wheels...

He set my shoes and then I test drove it with him and he then tightened the shoes a bit more ,,and all is good.. I shared all that you all told me about this system and he had a fun time working on them and what he learned from me from you all.. thx every one for all the info on this..

Directions are just another man's Opinion
