Rear disk!

[Stromtrooper james]

has anyone ever had any need to replace a rear disk brake disk.

I've been getting thought pads like oneo and now the disk its self has cracks in it and has turned a bit blue.

 any thoughts  on best place to get a replacement?
and how to reduce the amount of wear I'm getting?

Good used secondhand oem. Use less harsh pads on the rear.

Sounds like the brakes are binding, either the caliper needs stripping and servicing or you are riding the rear brake.

Rear brake pads should last ages, certainly longer than the fronts.  I have never replaced a rear disc, the one on my Vee had done 50k and still had loads of wear left.

If your rear rotor has cracks replace straight away . Excessive wear is generally down to a worn rear rotor or a seized rear caliper and , some people even ride the rear brake by keeping there right foot on the rear brake pedal without realizing it .
As for replacement , I would recommend nothing other than OEM , although others may disagree .

If it's turned blue it has been over heating and you need to find out why. The usual reason is due to the piston sticking in the caliper due to build up of dirt or corrosion and/or the caliper slider pins also sticking. It's also likely that the pads will be cooked as well. So all this needs resolving after getting a new disc before putting everything back together.
