I had the squeal REALLY bad, Changed mine out with 3/4 life left and went with something basic that claimed oe spec. quiet ever since. I too have been feeling the passion subside as I get pulled in other directions (not to mention the avalanche of car failures), as of late I finally got the car to reliable state with a compromise, The CEL just stays on lol. and after my tantrum a few months ago its been easier to deal with it being "imperfect" so its been easier to let the little things go, its been more enjoyable not stressing perfection and preservation of showroom condition. I have noticed the slow down this past year between my own and your posts, maybe when things settle down for both of us we can finally let the SHOs meet this year, and to keep this post about brakes, we can see if PP v nonPP matters in a stop test lol. Cheers friend (BTW, part of my separation from the forum has been 3D printing, I just added another printer and a scanner, so your project is still in que waiting on a prototype print)
