A horrible grinding sound from behind me suggested it was time to replace the Tour Easy’s rear brake pads:
Yeah, about half of the “Wear Line” text remains visible; the actual line is long gone to dust.
The retaining pin in the lower pad is twisted forward:
The pad wore enough to let it scrape on the rim, which certainly can’t be good for it.
The new Kool-Stop KS-MTTSA pads tout their leading wedge’s suitability for scraping mud off the rims, which isn’t a problem with my use case:
The odometer reports 20873 miles since the last battery replacement fumble.
The Smell of Molten Projects in the Morning 
You’ve been using your brakes?!? COWARDICE!!!
“When you get in trouble, screw on more power!”
Words to live by, or, for us, to get into more trouble …
I bought a pair of the Shimano pads today and was surprised to find that the retaining pin is no longer included. But a bent paper clip works better anyway.
By now, the riders who installed their pads backwards are all dead: no need for pesky pins!
