As per
Sierratim and his positive review of the KS-D635K pads, I ordered new pads (AERO Kool Disc KS-D635K) which I'll install tomorrow.
My existing OEM supplied pads which I changed to new SHIMANO J03A Resin Disc Brake Pads at 2300 miles, not that I needed to, but I was doing a bunch of other updates, new cassette, new chainring, new chain, new tires, etc., etc., I figured hey, why not new pads.
Nonetheless, they (I feel) were "bedded" correctly, but the front brakes squeal like a pig and I have been using them as an alert/sounding device (horn) when I come into an intersection where others are not acknowledging the sharing of the road, etc....... which I may miss....

Weird, the back ones are 100% silent.
So, after reading in-depth the discussions here, I figured
Sierratim knows his stuff, so I got the pads he says are meeting his expectations, so I'm following his suggestion to try them out.
They are about the same price.
Oh, yesterday while on a group ride, someone said to take the pads and soak them in boiling water to fix the squeal.....does anyone have a comment on that?
