Put the car up on jack stands. Disengage the e-brake. You will need to completely remove the calipers. You will see big azz bolts behind the calipers. You will probably need a breaker bar. Lift the caliper up off the rotor. Have your friend hold it, or you can disconnect it from the brake line. Once the caliper is out of the way, you can remove the rotor. My fronts came off pretty easily, but the rear ones were jammed in there from rust. Give it a few good wacks with a rubber mallet. You will see the caked on rust start to flake off. Clean the "hubs" the rotor mounts onto with brakekleen. Once you put the new rotors on, bolt the calipers back on. If you disconnected the caliper from the brake line, you will need to bleed the brakes. The service manual says to bleed the brakes regardless if you are replacing the brembo rotors.
You may need to bleed the brakes again after a drive. Sometimes air gets trapped in the ABS system. Oh yeah... you will make a huge mess. :P

What size were the "big azz bolts" holding the caliper on? I am looking to start my rotor replacement with a new set and couldnt find the size specs for those bolts? If you know it would be a great help in starting... thanks!

I've read through the service manual and saw the torque specs. However those bolts really are huge! okay...really big is more like it I suppose. They are bigger than the 19mm socket I had so I went out and picked up a 20mm and 21mm...looks like they are more like 25mm or somewhere up there.... perhaps everyone else used something else? If you took these off do you remember what size socket fit these bolts? Thanks for your help folks!!!

they are 21 mm bolts. don't bother taking off the caliper from the brake line, there is no need to.
just remember, these calipers scratch/nick very easily, so protect the caliper while working around it.

Who needs a second person , its called a bent coat hanger. If your worried bout scratching anything wind some duct tape around the hanger and disconnecting the brake line is just asking for more work.
Maybe i'm wrong here, but the brembos in the pic in the first post do not look like "real" brembo rotors. Brembo does not manufacturer drilled and slotted rotors, nor do their rotors have that many holes in them.
As someone stated in a previous post, they are probably brembo blanks with holes drilled into them, along with slots added. If that is the case, $900 for the set seems ridiculously high. I could be completely wrong...and i hope i am.

The BREMBO FRONT CALIPER BOLTS are 22mm and the BREMBO REAR CALIPER BOLTS are 19mm. I finally found the correct sizing after much hassle finding a socket kit bigger than 19mm. Someone mentioned 21mm being the front bolt size... The 22mm was very very snug on the bolts and the 21mm I tried didnt fit. That's my report on the sizing after some good old trial and error. And for those of you that wonder if there is something else holding the rotor on... there isn't. The backside of the rotor on my setup was rust sealed to the face of the lug plate. It was something crazy to break that rust but after some persistent spraying and some creative rubber mallet work it came off. I put the bolts back in with some antiseazing lubricant to hope make for a more pleasant time breaking bolts in the future.
