How do you change brake discs on a 1998 xj8 jaguar?

To change the brake discs on a 1998 Jaguar XJ8, start by safely lifting the car and removing the wheel. Next, remove the caliper by unscrewing its mounting bolts and then carefully hang it to avoid straining the brake line. Take off the old brake disc by unscrewing any retaining screws, then install the new disc in the reverse order, ensuring it's properly seated. Finally, reattach the caliper, replace the wheel, and lower the car before testing the brakes.
