Wrong. You shouldn't use automotive disc brake cleaner on bicycle brakes. Because they also contain oil as a surface protector. Car brakes being iron and all.
I've never had a problem with using this as a degreaser. I've got a couple of cans at home. I'll take a look at them later. The brake disk rotors on my motorbike are steel and they rust very easily.
I'd be surprised to see anyone using Stainless steel as rotor material as it is generally very soft.
