2001 Volvo S80 how do you change the front rotors

Remove the 7mm allen screws from the caliper and remove the caliper. Next remove the 15mm bolts on the caliper bracket to remove. Remove the 10mm bolt on the rotor and it should come off. Now depending on where you live, if there is a lot of rust on the hub, it makes it harder to remove. If you are replacing the rotors, grab a sledge hammer and pound it from behinde to remove it. Once you remove the rotors, get some sand paper or a wire brush and clean the hubs before installing the new rotors. Good luck :)
