I just recieved my Brembo rotors today. I'd like to install the rotors, but I'm pretty certain the OEM rotors will be siezed to hub with 7 years of rust. Anyone know the bolt/thread size to unseize the rotor?

7 years with same rotors is excellent longevity. Then I noticed you live in a dry country : Kansas City. Explains why. In my city, rotors last 3 years, 4 at most. They rust fast with a little help of road salt in winter.

Be sure to wire brush off all the rust on the hub surface, the rotors must sit as flat as possible. Also put some anit-seize compound on the hub/rotor mating surface so they dont get stuck in the future.

The biggest hammer you can find should do the trick if you don't ever plan on using the old rotors.

Oh another trick:

loosen the front wheel nuts a few turns, then lower the wheels on the ground, then turn the steering wheel right and left. The shearing pressure may help crack off the rusted rotors. Of course, this for is front wheels only.

Thanks for the bolt specs.

Kansas City isn't exactly dry, we do get snow from November to March, and they use lots of salt, but it's nothing like Canada My car has also spent nearly all of it's resting life in a garage and it gets washed at least once a week so that probably helps.

DAMN!

Here's what my suspesnion looks like at 170k miles in the Southeast



Plenty of dirt, but no rust. My brake rotors fall off by themselves when I remove the caliper...

You know what, in this rust country, if we leave any car sitting for too long, the surface rust on the rotors gets too thick. When driving off, the brake pads cant do as good as a job to wear off the coat of surface rust, compared to if only a very thin one night old only surface layer of rust was on the rotors. A few years ago, when my wife was taking her car only 2-3 days a week in winter, the rotors would get replaced every second year.

Just hit it with a hammer in a circular motion.
