I would agree that the quality is low, and the alum may indeed get brittle and be a part of some of the issues ...
but many of the issues are due to corrosion where the dissimilar metal adjuster screw (and assembly) and the alum casting meet...


I was just looking for a solution to help prevent corrosion and thought that anodizing will help.

I decided to bite the $50 bullet and just get it done. So i drove to the shop and i have now spent $10 in gas driving only to find out i need to remove the rivets and seperate the handle. So if i remove the rivet and return (another $10 in gas) and then go pick them up in 2 days.... It will cost me an additional $30 in gas. Grrrrr

I am now thinking rustolium (or similar) is the answer...
