I was getting a pulsing in my brake pedal so I naturally thought I had a warped rotor. As I started disassembling I realized it wasn’t warped it was bulging in one section were it was coming apart. As soon as I pulled off the hub /rotor assembly and set it on the ground the rotor completely split in half. If you look closely at the pic you can see small sections that look silver, those spots were the only thing holding the rotor together. The passenger side was the same way. I was shocked, I’ve never seen anything like this before.
