The squealing has popped up again, so let’s try testing an urban legend fix plan.<\/p>\n\n\n\n\n\n\n\n

There’s supposedly an urban legend that the pad material from back then doesn’t squeal…
In a way, you could say it was an era when non-organic materials were permitted…<\/p>\n\n\n\n

For now, let’s try with what we have on hand.<\/p>\n\n\n\n

We extract it, peel back the outer layer, and use it. We also adjusted the pad’s sliding condition.
Quite a bit of work…<\/p>\n\n\n\n

And just to be safe, we’ll hone-polish the disc surface.<\/p>\n\n\n\n

Before and after machining look like this. You get that nice whooshing sound you hear on a new disc again.

A homemade disc polishing machine… super analog.
It’s a pottery wheel with a lathe chuck attached to it…<\/p>\n\n\n\n

The key set replacement is complete, and on the test ride there’s zero squealing.
Now it’s just a matter of how things go once it’s fully bedded in.<\/p>\n\n\n\n

On the test ride, using the brakes quite a bit, the pad bite feels weak. However, this seems to be working in our favor\u2014softer abrasive materials might be gentler on squealing.

Cast iron pads might be quietly good too. Trying a pad replacement might open up a whole new world.<\/a><\/p>\n\n\n\n

All done! (^^\u266a
