  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

What could of caused this?

I was cleaning my wheels up and noticed the attached. I don't particularly use the rear brake so don't think its due to over heating, what could cause it to crack like that?

Are the rear discs the same on the 511 TE/TC/SMR?

Probably just general wear plus many heat cycles, maybe rapid heating then cooling. I've seen the same on car discs.
 
I've fried and worn my rear disks raw since forever. I've turned them blue. I've never seen one crack like that before...mebbe just a bad unit.
 
That is scary. My rear rotor is turning blue from the heat of some canyon riding. Even on knobbies. I may swap rear disc when I put the 17's on. These do not have much material on them.

Do you have a micrometer you can put on your rotor?

My rear is .132" thick (TE450) with 17,500 miles
Rear brake disc thickness (when new): 0.157"
Brake disc thickness at wear limit: 0.138"
