Hello i had a question last week about a scrape in my rotor, which i was able to sand out, per advice from this column (thanks). My question now is about trueness, while the sanding made it better, it's not perfect. When i lay the rotor on a flat surface to check for trueness, if i push down on the one side, the other raises about 1 to 4 mm. I know this means the rotor is bent but is this enough to cause a slight catching when i spin the rear wheel? Or are my problems somewhere else, the brakes are magura julies. When i spin the rear wheel hard, it goes maybe 4-6 rotations before stopping, making it not terrible but certainly not perfect.
thanks for the help.
