[Closed] Has anyone else melted their Ice-tech rotors?

sharkattack · 2013-08-23T10:20:47Z

Hello all, earlier this year I headed to Europe in the van for a couple of months and in the first 5 days of riding my brand spanking Shimano Ice-tech rotors were ruined. It appears that the alloy part of the braking surface sandwich has melted and oozed out and the steel part was worn down to half its width. I switched to the Avids from my spare bike and all was well again. When I got home the rotors went straight back to my LBS who sent them back to Madison. This was a month ago. I dropped in for an update and apparently someone from Madison has been on the phone quizzing them about how I was using the rotors. They want to know where I was riding, what bike I was on, whether or not I had entered the Megavalanche. All of which in my opinion is irrelevant. Their professional opinion was that I must have "had a stone caught in the rotor" causing them to overheat. Really Madison? I can't think of a situation where I could reasonably expect a set of brake rotors to wear out in less than a week. I've never worn a brake rotor out in the past, the Avids I switched to are 6 years old and still in perfect working order. My LBS still don't know whether or not Madison intend to replace or refund them. I was under the impression that Madison were quite good and we're not sure why they're dragging their heels. I was just wondering if anyone else has had the same problem.

If I were Madison I'd want to know as much about the cause as possible, Shimano will have to redesign them based on your info to an extent.

Shouldn't Shimano be doing their own R&D under controlled conditions, not relying on third hand anecdotes?

Aluminium is a fairly soft metal, and enough force from the caliper could squeeze it out of the rotor even at room temperature.

An aluminium caliper?

I'm using a XT Shimano XT RT86 Ice-Tec 180mm 6-Bolt Rotor with finned Shimano pads/ XTR calipers and levers (trail flavoured)

Pads are less than a month old, rotors are a year old.

Including the OP, ive heard off one other instance of this happening (ie 3 instances). Still reckon its a defective disc (crack in alu?) rather than a design flaw. Have emailed Madison.
