Spray the bolt and around the hub with penetrating oil. Do it again in an hour. Let it sit overnight.

Remove the bolt on the front side of the rotor.

Rotors should be replaced when pads are replaced so it doesn't matter if you hit the face of the rotor. Get a bigger hammer! I have a steel head hammer I use to drive railroad spikes. Whack the front of the rotor around the outer face. whack it as hard as you want. It won't hurt anything and might even come off.

Before hitting the back of the rotor look at the metal shield so you will know how far away from the rotor and what the shape should be as you might hit the shield and you will need to get it back to original shape and distance from the rotor.

Then put two hands on that big a#s hammer and whack the back side on the bottom of the rotor. You may have to whack it many many times and as hard as you can but it will come off. You can rotate the hub if you want but I have never needed to do so.

Be sure you don't have a part of your body where the rotor will fall.

Before you install the new rotor wire brush the hub and put some high temp anti-seize grease on the bolt and the hub.

Would you like some input on the pad removal/ install or are you familiar with the process?
