Movement in Right Rear Drive Axle
 

I replaced the rotors, calipers and pads on all four wheels of my 2005 Blazer a couple of weekends ago. The right rear wheel was the only area I encountered some resistance when it came to pulling off the old rotor. I had to hammer it off because it just wouldn't let go. It was the emergency brake holding it in place. Odd since I'd never used the emergency brake since I bought the truck new in 2005. Once I had everything cleaned up and was setting the new rotor into place I noticed I could pull the mounting flange in and out about 1/8". Is this a normal amount of movement or is there a chance I may have damaged something while hammering the old rotor off? I didn't think I'd hit it hard enough to cause damage.

It's ok, just how they are.

Thanks. I was concerned, especially since the old break pads were worn down to the metal on that wheel. I think I'll just keep a closer eye on it from now on.
