Re: at wit's end
swapped rear arms to front while waiting for paint to dry - no improvement
paint dried (& looks like painted by old people) - arms are about 4mm thicker at pad mount point (had to remove the large alignment spacer because pad posts are way too short to make that extra 4mm mount) - brakes are silent now : )
arms are so much shorter that cable drags on fender with fender mount as low as possible & a bit of extra bend applied to fender, but they return OK & work well so good enough
will save these china arms for possible use on rear of something since they were silent there
may stop buying boxed bikes so I can listen to brakes at the store (altho I was about to order 3 magna bikes over inet today)
Sometimes I sets and thinks, sometimes I jes sets.
