The four wheel disc brake system on a Jaguar XJ8 consists of front and rear brake pad sets, four rotors, four brake calipers and the hydraulic system. While most of the components should last the life of the Jaguar, the brake pads and rotors will wear out with regular usage. Repairing a Jaguar can be very expensive, but if you have basic automotive repair skills, you can save some money by changing the front brake pads on your XJ8 yourself.
Turn the front lug nuts counterclockwise with the lug wrench until they’re all hand tight. Do not take them off.
Position the wheel chocks around the right-rear wheel to prevent the Jaguar from moving when you lift the front end.
Raise the front of the Jaguar with the jack and then lower it onto the jack stands, placed under the front frame on both sides.
Remove the front lug nuts and wheels by hand, then set them off to the side. Do not to misplace any of the lug nuts.
Place the catch pan under the left-front brake rotor. Rinse the brake rotor and caliper thoroughly with the brake cleaner to remove leftover brake dust.
Unbolt the brake caliper with the socket set and lift it out of the caliper bracket by hand. Pull the old brake pads out of the caliper by hand and discard them.
Clean the inside of the caliper with brake cleaner, then lubricate the caliper slides with white lithium grease.
Move the pistons back into the caliper with the caliper tool. Place the new brake pads in the caliper and slide the caliper into the caliper bracket. Bolt the caliper to the bracket with the socket set.
Repeat Steps 5 through 8 on the right-front, then reinstall the wheels and lug nuts. Lower the Jaguar off the jack stands with the jack, move the wheel chocks away from the back tire and tighten the front lug nuts to 85 foot-lbs. with the torque wrench.
