Frequently Asked Questions

The Brembo 09.7217.21 is an OE-equivalent rear vented brake rotor for Jaguar XJ6, XJ8, XJ12, and XJR models manufactured to match the factory Brembo specification. It features a 305mm disc diameter, Prime UV anti-corrosion coating, and a 5-hole bolt pattern for direct bolt-on fitment.

The Brembo 09.7217.21 fits the 1995-1997 Jaguar XJ6, 1998-2003 Jaguar XJ8, 1995-1996 Jaguar XJ12, and 1995-2003 Jaguar XJR as a rear axle replacement rotor.

Each order of the Brembo 09.7217.21 includes 2 rotors per box, covering one rear axle. No separate pair purchase is required.

The Prime coating is Brembo's UV-cured anti-corrosion treatment applied to the non-braking surfaces of the 09.7217.21. It prevents surface rust during storage and shipping and helps maintain a clean appearance during the service life of the rotor, particularly on vehicles that sit for extended periods.

The Brembo 09.7217.21 replaces the earlier Brembo 09.7217.10 and the untreated variant 09.7217.20. It is a direct dimensional equivalent to both predecessor part numbers.

Brembo specifies a minimum serviceable thickness of 18.5mm for the 09.7217.21. The rotor should be replaced or machined to within this specification at each brake service inspection to ensure adequate stopping performance.

No. The Brembo 09.7217.21 is a smooth-faced vented OE-style replacement rotor. It is not drilled or slotted, which matches the original equipment specification for these Jaguar XJ models.

Brembo specifies a tightening torque of 103 Nm for the wheel bolts when mounting the 09.7217.21, consistent with the factory Jaguar XJ torque specification for rear hub hardware.

Installation Instructions

1. Safely lift the vehicle and support it on jack stands before removing any brake components.
2. Remove the rear wheel and tire assembly to expose the brake rotor and caliper assembly.
3. Slide off the old rotor; if it is stuck, apply penetrating lubricant to the hub mounting surface and use a rubber mallet to loosen.
4. Clean the hub face and bearing surface of any rust, debris, or old grease before installing the 09.7217.21.
5. Remove the Prime protective coating from the braking surface using brake cleaner spray; wipe dry with a clean cloth.
6. Slide the new 09.7217.21 rotor onto the hub, aligning the 5-bolt holes with the wheel studs.
7. Temporarily secure the rotor with one lug nut to hold it in position during caliper reassembly.
8. Inspect and replace brake pads as needed; compress the rear caliper piston and reinstall the caliper.
9. Reinstall the wheel and tighten lug nuts to the Jaguar factory torque specification (103 Nm).
10. Bed in the new rotors by performing 5 to 10 moderate stops from 35 mph, allowing 30 seconds of cooling between each stop, before returning to normal driving.
