Do EVO pads fit in KoolStop holders?

I've never crashed in the rain because of brake failure (and I've crashed many times in the rain), although I had one close-call involving some bad cantis on STI levers, but then again, I had an even scarier incident with mis-adjusted cable discs. My crashes were all due to traction loss. One of my really nasty crashes happened when the front brake cable snapped. It was almost new. That just does not happen with hydraulic disc brakes. I had the choice of wiping out with major road rash or chancing it into the vegetation. In either case I'd have been toast if there had been oncoming traffic. A catastrophic failure can happen in any system. Breaking a new cable is a catastrophic failure. It shouldn't happen (it's never happened to me in maybe 300K miles of riding). I had it happen half a dozen times. My sister had it happen at least twice. Two of those incidences caused accidents, a 3rd almost did (blowing through a non 4-way downhill stop sign but nobody came). These were all good quality cables bought at reputable bike shops, not department store merchandise. A half a dozen times? And your sister, at least twice? It seems to me that you need to find a four leaf clover, or carry a St Christopher medal on your bike to protect you. Or maybe a verse from the Koran? Something anyway, as you obviously are suffering from incredible bad luck. In contrast to your experiences, I rode my first bicycle in about 1943 and have ridden bicycles and motorcycles and airplanes, all of which depended on cables to control them, and have never experienced a broken cable. With all your cable problems I'd think that a "dead weight" cable tester would be to your advantage. Simple to build and simple to operate it would ensure that your cables met the necessary strength requirements. ... You could get the same failure with defective hydraulic tube or joint, piston, pad holder, mounting bolt, etc. You could get a leak ... Those are slow, you'd feel it coming. Things don't just snap. ... -- you could even blow through a pad set on a single ride. That must be a long hard competition ride. ... A giant earthquake could wipe out your hydraulic calipers! Yes, I suppose that could happen. Or a direct meteorite hit into the left lever. [...] ... I switch between disc and direct mount caliper brakes on the weekends and find that braking is great on both. Thanks for the hint about the Koolstop pads. They just came. Ebay tracking is a nice "mail is here" alert. It came early today. They fit like a glove. I wonder why they now flare the trailing edge inwards towards the rim. It would make the pad want to skew. Maybe I'll grind that off. No. It's meant to wipe the rim before the pad fully engages. It is exactly what you want for dirt and wet weather performance. Let's see. I could almost bet that pointy tip will be worn away after a few hundred miles. Depends on the 100 miles, but yes, it's not going to last forever. My disc pads last about one-quarter the time of my rim brake pads. Time to upgrade the disc brakes? Mine last about the same and that is comparing a road environment for the rim pads to 90% trail riding on the MTB. Dusty, mucky, wet and gravely trail riding. Sometimes when a stench develops I have to pry "brake mousse" out of the front caliper. That happens after the weeds shot up and have to I ride through them for miles. Star thistle is particularly nasty. It tangles in the rotor spider, then gets chopped and pureed at the caliper. Doesn't cause performance issues but it can stink. What wears really fast are organic pads. The kind bike shops sell you for north of $15/pair. I like ceramic-based pads. You can't use cheap rotors with those though, they'd eat them up. I use Shimano RT66 rotors. They cost me $22 each, 8-inchers. -- Cheers, John B. |
