Has anyone seen or experienced this before?
I can't imagine this is normal, I assume this should be replaced? And I'm trying to figure out how to prevent thi from happening again.
This is on the rear of a tandem
Warped rear rotor. Why/how does this happen?

How thick is the rotor?
Definitely needs to be replaced. It’s from heat. Back end of a tandem riding the brakes will get crazy hot. I’d switch to a thicker rotor as long as it’s compatible with the brake caliper, and also get metallic pads which should shed heat better.
That’s awesome, never seen this!
It shrunk after severe overheating, but that’s not typical.
It also looks this rotor is meant for wide style of brake pads, while your brakes are narrow (see the strip of unused surface on inside edge). I bet that contributed to the warping.
So I would buy a different brand of rotor, and also one that’s meant for narrow style of pads, so it’s all covered and heated evenly.
And maybe chill out on the barkes, but IDK 😉
Holy s that’s a first for me. Id replace with a 203 mm at least and I’d do the same up front.
