re: '... there still being some residual brake fluid on the drum
(even though I thought I had cleaned it all off) ...'<br>
<br>
Can't be done. I tried once, by cleaning--with brake
cleaner--sanding the 'wet' off and repeat repeat repeat. I thought I
had some cleaned, but after sitting overnight brake fluid would ooze
out, no matter how many times I tried to clean them. Maybe, if it's
a light 'dusting' of fluid, and you get to it immediately you can
have some success, but who wants to take any chances with brakes?<br>
<br>
FWIW, I've 'voided the warranty' several times using silicone BF
with no issues (I have had problems with DoT 3, though). I don't
recall the 'Classic Gold' cylinders I got from Moss having that
warning on the box. I was grateful to pay a reasonable price for
front cylinders for a BN2; years ago they were something like $70
per for F/R. I never figured out why, just for the front rights, but
we got one that was obviously a return (slightly) cleaned-up and put
back on the shelf. Moss, among others--looking at you,
RockAuto--apparently put returns back on the shelf without
inspecting them.<br>

<div dir="ltr">Hi Michael - to elaborate - after a few miles of

<div>In retrospect, that was probably exacerbated by there still
