Choosing the Right Aftermarket Brake Pads for Your 1998-2009 Jaguar XJ8
Stop the squeal and excessive brake dust by selecting the correct disc brake pads for your specific Jaguar XJ8 model.
- Identify your car's generation: X308 (1998-2003) or X350 (2004-2009), as brake systems differ.
- For 2004-2009 models, rear brake replacement requires a special procedure to retract the Electronic Parking Brake (EPB).
- Choose aftermarket ceramic pads like Akebono or Bosch to significantly reduce brake dust compared to OEM.
- Visually confirm if your car has standard or optional Brembo/performance brakes, as they use different pads.
Understanding Your XJ8's Brake System
Before buying brake pads, you need to know which Jaguar XJ8 you have. The model was produced across two distinct generations, and their brake systems are different.
- X308 Generation (1998-2003): These models use a traditional braking system. The front and rear brake pad replacement is straightforward for a mechanic or experienced DIYer. 🎬 Watch a full front and rear brake pad replacement guide. Some high-performance XJR models came with optional Brembo-branded calipers, which require specific pads.
- X350/X358 Generation (2004-2009): This generation introduced an Electronic Parking Brake (EPB). While the front brakes are similar to the earlier models, replacing the rear pads is more complex. The EPB must be put into a service mode or retracted before you can compress the caliper piston. Failure to do this can damage the EPB actuator. Some supercharged models also came with larger standard brakes or optional Alcon or Brembo performance brakes, which use different pads.
Electronic Parking Brake Warning (2004-2009 Models)
Replacing the rear brake pads on an X350/X358 requires putting the Electronic Parking Brake (EPB) into service mode. This can be done with a Jaguar-specific diagnostic tool or by following a specific manual procedure, which often involves disconnecting the battery after releasing the brake. Attempting to force the caliper piston back without retracting the EPB will cause damage. If you see a 'NOT CALIBRATED' message after the job, a recalibration procedure is necessary.
OEM vs. Aftermarket Pads
Original Jaguar brake pads, often made by brands like Textar or Pagid, provide a good balance of performance and feel but are known for producing a heavy amount of black brake dust. Many owners switch to aftermarket pads to solve this problem. High-quality aftermarket pads can offer significant improvements in dust reduction and sometimes even stopping power, without sacrificing safety.
Choosing the Right Aftermarket Brake Pad Brand
With so many brands available, it's best to choose based on your priorities. The pads can be grouped into tiers based on what they do best.
| Pad Type | Best For | Popular Brands | Pros | Cons |
|---|---|---|---|---|
| Low-Dust Ceramic | Daily driving, clean wheels | Akebono, Bosch QuietCast | Very low dust, quiet operation, long life. | May have less initial "bite" or stopping power than semi-metallic pads. |
| Performance / Sport | Spirited driving, enhanced stopping power | EBC (Redstuff, Yellowstuff), Hawk HPS, Brembo | Excellent stopping power and heat resistance. | Can produce more dust and noise than ceramic pads; may wear rotors faster. |
| OEM-Equivalent | Restoring factory feel and performance | Textar, Pagid, TRW, ATE, Jurid | Designed to match the original pads' performance characteristics. | Likely to produce significant brake dust, similar to the original pads. |
| Daily Driver / Standard | General use, budget-conscious repairs | Centric, Raybestos, Wagner | Affordable and reliable for everyday driving needs. | May not offer the performance or low-dust benefits of specialized pads. |
Known Issues, Recalls, and TSBs
While there are no recalls specifically for brake pads, there are related issues to be aware of:
- NHTSA Recall 09V-144 (Jaguar J012): Affects some 2004 XJ models. Corrosion of underfloor brake pipes could lead to reduced braking performance or a complete loss of service brakes. Dealers were to inspect and, if necessary, replace the corroded pipes.
- TSB for Brake Noise: Jaguar issued a technical service bulletin for 2006-2008 XJ models regarding a click or squeal during light braking. The fix involves replacing front brake pads and applying special grease to contact points.
- TSB for EPB Calibration: A bulletin exists for 2003-2009 XJ models outlining the correct procedure to recalibrate the Electronic Parking Brake after service, which is necessary if it fails to operate correctly or displays a warning.
Pro Tip: Check for Brembo Brakes
Before ordering, visually inspect your brake calipers. High-performance XJR models or cars with special-order packages may have larger calipers, often branded with "Brembo" or "Jaguar R". These require different, model-specific brake pads. Always confirm your brake type to avoid ordering the wrong parts.
Frequently Asked Questions
Should I replace my brake rotors at the same time as the pads?
It is highly recommended. Installing new pads on old, worn, or warped rotors can cause noise, vibration, and reduced performance. For best results, replace pads and rotors together. 🎬 See how to replace front brake pads and rotors. If you reuse rotors, they should be inspected for thickness and surface condition.
What is the difference between ceramic and semi-metallic pads?
Ceramic pads are made from dense ceramic materials and are known for being very quiet and producing a fine, light-colored dust that doesn't stick to wheels. Semi-metallic pads contain metal fibers, which help dissipate heat and provide a stronger initial bite, but they typically create more noise and dark dust.
Why are my new brakes making noise?
New brakes can sometimes squeal during the "bed-in" period as the pad surface conforms to the rotor. This usually goes away after a few hundred miles. Noise can also be caused by not applying brake grease to the pad backing plates and caliper contact points during installation, or by installing new pads on old rotors.
Do I need to replace the parking brake pads?
For most XJ8s, the main rear brake pads are also used for the electronic parking brake. However, on models equipped with Brembo brakes, there may be a separate, smaller set of pads just for the parking brake function. These parking brake pads wear very slowly and rarely need replacement unless used to stop the car in an emergency.
