Rear rotor warped?

[Randy McClure]

Noticed the other day when adjusting belt tracking that the rear pulley (parking brake cable) was moving in an out kinda like when you had an old vinyl record that was warped and the needle arm would move up and down. Sounds like a warped rotor to me. Also when spinning tire by hand I could feel it drag in one certain place. Any thoughts?

Probably perfectly normal.

Most rotors have a little "run out" and have a tiny drag somewhere.

And many times what is described as "warped" really is a bad spot (hard or soft) in the metal that is caused by overheating......or bad material when new or really BAD corrosion.

ill double check before ordering new rotor.

but if you want to make sure you need a new rotor you can remove it and place it on a flat surface and mesure it. Or if you have a run-out micrometer measure it as the wheel turns. Many times brake pads also hang up giving you some drag as they move back...
