Brakes problem
2005 Volvo S80 Front Wheel Drive Automatic 55000 miles

I am having trouble removing a brake rotor. I have removed the brake and caliper and hub bolt and I am having trouble getting it worked free. Doesn't seem to budge at all. Am I missing something? What else should I do?

updated 4-14-09
I
replaced my front brakes and rotors. I test drove the car and noticed a rubbing sound like metal on the right side. I drove about 2 miles and stopped and noticed a grove starting to form on the right rotor. I have no issues on the left side. Here are some things I noticed when I was re-installing the caliper: The caliper mounting bolts didn't screw in and stuck out further compared to before I removed them. Also, There is a wire spring clip that goes on the outside of the caliper facing the tire. It was very difficult to get back on and I still don't have it exactly like it was before removal. What could I have done wrong. Is it possible that I bought the wrong pads. This is a little frustrating because now it looks like I am going to have to replace a new rotor.

Thanks

Once the hub bolts and caliper are removed, the only thing holding the rotor to the hub is rust. No, WD40 won't do, you need some rust catalyst such as PB Blaster, available at your local auto parts store. Using the straw (should come with the can), spray through the hub holes (all of them), and if you have access, from the back as well. Wait about 5 minutes, and then use a rubber mallet to break the rotor free.

Here is the reason for the delay is response.

Anyway.

You may want to remove the wheel on the driver side, and see how the caliper and pads on that side are installed. The passenger side should be the mirror image of the driver side.

Here is how the caliper should look like attached to the caliper bracket. Remove the caliper bolts. See if the threads on the bolts and on the bracket are damaged. If they are, either replace the bolt or repair the damaged thread on the bracket. Use tap/die set for that.

I don't have a picture showing how the spring looks like on the assembly. How did you get the other side on? Try to attach it similar to the driver side. Is it possible that the spring is damaged? I do believe this is how the spring is attached to the pad, through the outside of the caliper.

Not if the other side works just fine. Anyway, list the part number that you purchased. I can cross-reference it to my database. It should be in this format: XXX794XXX. "X" can be any digit or alphabet. It will be on the box.

Not necessarily. If it is just a scratch, you can bring it to O'Reilly and they can turn it smooth. Unless, the groove is too deeply-gouged.

Here is the part number on the box: MX794
There is another number below that: MX7664
"Wagner Thermo Quiet"

THe Caliper mounting bolts on both sides did not seat as deep in the rubber boot as before. I will check threads as you directed.

The spring clip on the driver side was difficult to get on. I took pictures of it before I removed it to make sure I got it back on correctly. I used a screwdriver and needle-nose pliers to seat it.

I will remove the rotor and take it to O'Reillys

You have the correct brake pads for the front.

While removing the the caliper bolts, check and feel if the bolts coming straight out or feels too tight (cross-threaded) and/or coming out at an angle (either bent bolt or bolt went in not straight)

Screw driver and needle nose pliers are all you need. I also sometimes use a pair of dikes (so I can get a good grip on the spring with force, but not enough force to cut the spring in half).
