Update on my 1595 1/2 RC. I ordered the spring cam and brake screw from eReplacement parts.
I pried up the screw retainer, it was tough! A screwdriver did it, along with some paint damage, oh well.
Then I simply put in the new spring cam and threaded the new screw through, then used a punch and hammer to get the retainer back down
When I began the repair the broken spring cam (half of it) was still on the spring and I was using it as a leverage point to pry up the retainer, when I did this a piece of the cam just sheared off. Maybe it was a bad batch of steel or something, but very brittle and strange. The rest of the reel seems pretty solid even if made in China. Next, I'm going to go and put blue Loctite on all the screws, should be pretty bombproof, hopefully. I have a 1595 RC too. I sold off my vintage medalists, but at some point I'll get a few of the classics. Oh and the original screw maybe had a speck of marring on one area of the threads but it looks fully functional. I replaced it anyway. If anyone is in desperate need of a brake adjustment screw, contact me.
