NotSoBigBen Posted April 20, 2011 Share Your generalising while I’m referring specifically to brake systems. Brake systems are not that unreliable that they can be included amongst the normal mtb technical problems like punctures, broken chains, bent derailer / hangers etc… Out of 1200 that started the epic I wonder how many actually suffered a brake component failure that was due to a component flaw? For most of the 1200 brakes was the least of their problems Link to comment Share on other sites More sharing options...
covie Posted April 20, 2011 Share Not sure what the point of this discussion is anymore lol, the dude either had a brake failure or just saw his ass. A lot of us had brake failures and wipeouts in our lifetimes so both are plausable. Not even sure the manufacturers will try and analyze this as indepth as hubbers do. No worries Mr Evans next year Link to comment Share on other sites More sharing options...
Cassie Posted April 20, 2011 Share So....did both front & rear brakes fail? What are the odds of that happening - all at once? Link to comment Share on other sites More sharing options...

No worries Mr Evans next year Not all of us were involved at the beginning of the discussion And its an internet forum not a library book which has to be returned by a certain date. I guess the point after all the preceding pages would be to try and establish if:1. Some part of the brake system was at fault.2. Which part and and who makes it.

SwissVan Posted April 20, 2011 Share For most of the 1200 brakes was the least of their problems LOL In my case i reacon my brakes worked a lot harder than KE's brakes, heavier all up weight and significant more time spent braking... Did i already mention my brakes worked flawlessly Link to comment Share on other sites More sharing options...
SwissVan Posted April 20, 2011 Share And out of those that did have failure, how many used the same components as Evans. Do we know what he used for sure? Probably very few used the same components, perhaps there is a reason or 2, one being cost and the udder.... oh wait strike that from the record your honour...

Gravity Sux Posted April 20, 2011 Share Ok, so here's a stick in the spokes.I have read some of the threads on here and noticed all the speculation aimed at his front brake having failed. I watched the coverage and never heard him say once that it was his front brake.1)So what happend to the rear brake if this was the case? This is also a very good way to stop, pull the other brake!! 2)What is the 1 in a million chance of both front and rear brakes failing at the same time? 3)If it was his mechanic, why did the brakes not fail sooner? 4)if it was brake fade, he would have felt this coming on during a few brakes before then? All pro's do experience a "brake" in concentration (see any road race and the amount of crashes). So could it not be that he just lost concentration for a split second, over estimated the downhill and never managed to get control of the bike?We are all human. it happens. If this is the case, it would be very sad that he blamed it on brake failure. Because a statement like that is really bad publicity for a bike and product. Its far easier to blame something else than to admit it was your own mistake.We all do it. I feel very sorry for Kevin and George.Kev, good luck and get well soon. If you saw the hill he fell on that front brake failure = no brakes. It was very steep and rough (tree roots / rocks) and to make things worse there was so much dust that there was no choice of line. On a rough, steep descent back brakes do very little as all your weight is on the front. Also, he was not the only rider to fall on this hill and injure themselves, just the highest profile rider to do so. Link to comment Share on other sites More sharing options...
kandui Posted April 21, 2011 Share Hi Drongo, or is it "the Drongo"?I rode 2011 XTR brakes and rotors at the Epic and they gave me zero problems. The braking power for a true one finger brake is awesome. The brake pressure control is also superb.I heard at the Epic that Kevin was using an Aluminium rotor which seized due to the heat build-up. Can't take this a gospel , but heard if from someone who was working with the winning Masters team.New XTR is a real jump forward, I recommend them highly.

kosmonooit Posted April 21, 2011 Share Would be interested to know if indeed the rotors did fail which ones they were. Cant imagine anyone in their right mind using Al rotors. Maybe some composite with an Al sandwich and harder steel faces.. .? Link to comment Share on other sites More sharing options...
neelst Posted April 23, 2011 Share Ai ja jai. Rotors dont fail from braking. Rotor bolts and centre locks dont fail from braking. Hydraulic hoses can fail. Brakes fade if too hot, get spongy with air and dont work at all if a hose has failed. Those are the three options. No one will ever live to see a stainless or alluminium rotor.

kandui Posted April 26, 2011 Share Like I said, this is what I heard from someone working with one of the pro teams. Was a heat issue. Aluminium does sound unlikely, but fact is that material failure was to blame. Link to comment Share on other sites More sharing options...
