A Guide to the Disc Brake Hardware Kit for the 2000-2007 Jaguar XKR
Eliminate brake noise and restore proper caliper function on your Jaguar XKR by replacing this often-overlooked kit.
- Always replace the disc brake hardware kit with every brake pad and rotor change on a 2000-2007 XKR.
- Properly lubricating the new caliper guide pins and pad contact points is critical to prevent noise and seizing.
- Symptoms like noise, pulling, and uneven pad wear are often caused by failed hardware, not just bad pads or rotors.
- If you own a 2007 XKR, check if your vehicle is affected by the brake servo hose recall (J003).
Why Your XKR's Brake Hardware Matters
On a performance car like the Jaguar XKR, the braking system's precision is paramount. While brake pads and rotors get most of the attention, the small metal clips and pins in the disc brake hardware kit are just as important. After years of exposure to intense heat, moisture, and road salt, this hardware corrodes and loses its ability to function correctly. Original hardware on a 2000-2007 model is well past its service life. Ignoring it during a brake job can lead to persistent noise, premature pad wear, and compromised braking performance.
Symptoms of Worn Brake Hardware
Failing brake hardware often mimics other brake problems. Here are the common signs:
- Squealing or Rattling: This is the most frequent symptom, caused by worn or missing anti-rattle clips that allow the brake pads to vibrate.
- Vehicle Pulling to One Side: If a caliper guide pin is seized due to corrosion, the caliper cannot slide freely. This can cause the brake on that wheel to either drag constantly or not apply with full force, making the car pull to one side when driving or braking.
- Uneven Brake Pad Wear: A sticking caliper will cause the inner and outer brake pads to wear at different rates. When you replace your pads, if one is significantly thicker than the other, seized hardware is the likely culprit.
- Burning Smell: A caliper that is stuck due to a seized guide pin will cause the brake pad to constantly drag on the rotor, generating extreme heat and a noticeable chemical or burning smell from one wheel.
Known Issues: 2007 Jaguar XKR Brake System Recall
The NHTSA issued a safety recall (J003) for some 2007 model year XKR supercharged vehicles. The brake servo vacuum hose could have been routed incorrectly, allowing it to touch a hot valve and melt. This can cause a vacuum leak, leading to a hard brake pedal and increased stopping distances. While not a hardware kit issue, it is a critical safety check for any 2007 XKR owner.
Choosing the Right Aftermarket Hardware Kit
For a part like a disc brake hardware kit, you do not need to seek out an expensive OEM Jaguar part. Quality aftermarket brands provide reliable components that meet or exceed original specifications. The most critical factor for success is not the brand, but the fact that you are replacing the hardware with new, clean, and properly lubricated parts during every brake service. Brands like Carlson, Centric, Dorman, and Dynamic Friction all offer kits for the XKR.
- Standard Replacement (Carlson, Dorman): These brands are widely available and provide a dependable, cost-effective solution that is perfectly adequate for street driving.
- Enhanced/Performance (Centric, Dynamic Friction): These brands are often well-regarded in forums for their broader brake component lines. While their hardware kits are similar to standard replacements, they sometimes feature better coatings or materials. Given the small price difference, they are a solid choice.
Pro Tip: The XKR was available with standard (Teves) or optional Brembo performance brakes. These systems use different hardware. Be absolutely sure to order the kit that matches the brake system on your specific car.
| Brand Tier | Price Range |
|---|---|
| Standard Aftermarket (e.g., Dorman, Carlson) | $7 - $15 |
| Premium Aftermarket (e.g., Centric, Dynamic Friction) | $12 - $22 |
Frequently Asked Questions
Do I really need to replace the hardware with every brake job?
Yes. For a vehicle of this age, it is essential. The old clips have lost their spring tension from thousands of heat cycles, and the guide pins are likely corroded. Reusing old hardware is the number one cause of noise and caliper issues after a brake job. The low cost of a new kit makes it cheap insurance.
What is the most important part of installing a new hardware kit?
Lubrication. The caliper guide pins must be cleaned and lubricated with a proper high-temperature synthetic brake grease. The areas on the caliper bracket where the anti-rattle clips and brake pads make contact should also be cleaned of rust and lightly lubricated. A Jaguar Technical Service Bulletin (TSB #00008) was issued for 2006-2007 models specifically to address cleaning and greasing pad anchor surfaces to prevent noise.
What's included in a typical hardware kit?
A kit for one axle (two wheels) usually contains all the necessary anti-rattle clips/springs, and may also include new caliper guide pins and protective rubber boots. Always check the product description to confirm contents.
Can I just clean and reuse the old clips and pins?
While you can try to clean old parts, it's not recommended. Anti-rattle clips are spring steel and lose their tension over time, so cleaning them won't restore their function. Guide pins can have microscopic pitting from rust that will quickly shred the new rubber boots and cause them to fail again. Given the low cost, replacement is the only reliable option.
