A Guide to Your 2003-2008 Volvo XC70's Disc Brake Hardware Kit
Eliminate annoying brake rattles and ensure proper function with the right hardware for your XC70.
- Always replace your disc brake hardware when changing brake pads to prevent noise and ensure even wear.
- Rattling noises from the wheels, especially over bumps, are a primary symptom of failed hardware on an XC70.
- Quality aftermarket brands like Centric and Raybestos offer excellent performance and value for this part.
- Be aware that rattling from the rear can also be caused by the separate parking brake hardware inside the rotor hub.
Symptoms of Failing Brake Hardware
Worn or missing brake hardware on your XC70 can cause several distinct problems. Ignoring them can lead to more expensive repairs down the road.
- Rattling or Clunking Noises: This is the most common symptom. You may hear a metallic rattle or clunking sound from the wheels, especially when driving over bumps. This noise might disappear when you apply the brakes, which temporarily presses the loose pads against the rotor. This happens when weak or missing anti-rattle clips allow the brake pads to move around in the caliper bracket. 🎬 Watch this video to hear and fix a common brake rattle.
- Squealing or Scraping: While often blamed on the pads themselves, improper hardware can cause pads to sit at a slight angle, leading to high-frequency vibrations (squeals) during braking.
- Uneven Brake Pad Wear: If the hardware that allows the caliper to slide is corroded or stuck, the brake pads can wear unevenly. You might find the inner pad is much more worn than the outer pad, or vice-versa.
- Spongy or Ineffective Brakes: In severe cases of hardware failure or corrosion, the calipers may not apply or release pressure correctly, affecting braking performance.
A Note on Parking Brakes
The 2003-2008 XC70 has a separate parking brake system with brake shoes inside the rear rotors. This system has its own springs and hardware. A rattling noise from the rear can also be caused by worn parking brake hardware, a common issue on these Volvos. If you're replacing rear brake hardware to solve a rattle, it's wise to inspect the parking brake components at the same time.
🎬 Watch how to replace the parking brake shoes and hardware.Choosing the Right Aftermarket Hardware Kit
When you replace your brake pads, you should always install a new hardware kit. Reusing old, heat-cycled, and rusty clips is a recipe for noise and poor performance. For the 2003-2008 XC70, there is no significant quality difference between OEM and a high-quality aftermarket kit. The key is choosing a reputable brand.

Not all aftermarket parts are created equal. Here’s a general breakdown of the available brands based on owner feedback and general reputation.
- Premium Aftermarket (Centric, Raybestos): These brands are often considered the go-to for a good balance of quality and value. Forum discussions frequently show users having positive experiences with both, noting good fit and materials. They are a reliable choice that should perform as well as the original parts.
- Standard Aftermarket (Dorman, Dynamic Friction, Carlson): These brands offer a dependable, budget-friendly option. Dorman is known for creating direct replacement parts that match OEM specifications. Dynamic Friction is seen as a solid value brand. Carlson sometimes offers innovative designs, like clips intended to reduce brake drag. These kits are perfectly suitable for daily driving.
- Repackagers (Beck Arnley): Some brands source their parts from various manufacturers. Beck Arnley is a well-known example. The quality can be excellent, but it may vary depending on who manufactured the parts for that specific box.
Cost to Replace Disc Brake Hardware on a 2003-2008 Volvo XC70
The hardware kit is almost always replaced as part of a brake pad and rotor job. The cost of the kit itself is minimal compared to the overall job cost. The prices below reflect the cost for one axle (either front or rear).
| Part/Service | Estimated Cost |
|---|---|
| Aftermarket Disc Brake Hardware Kit | $10 - $41 |
| OEM Disc Brake Hardware Kit | $30 - $70 |
| Shop Labor (as part of brake job) | $100 - $250 per axle |
Frequently Asked Questions
Can I reuse my old brake hardware?
No. The old clips and springs have been exposed to thousands of heat cycles, moisture, and road salt. They lose their tension and rust, which is why they fail. A new kit is inexpensive and ensures your new brake pads work correctly and quietly. It is false economy to skip it.
What is included in a typical disc brake hardware kit?
A kit for your XC70 will typically include all the necessary anti-rattle clips and springs for one axle (both the left and right wheels). Some kits may also include new guide pin boots or bolts, but this varies by brand. Always check the product description to see what's included.
Do I need different kits for the front and rear brakes?
Yes. The front and rear brake calipers on the XC70 are different sizes and use different hardware. You must buy a kit that is specifically listed for the front or rear of your vehicle.
What are the torque specs for the caliper bolts?
While this can vary slightly, a common torque spec for the caliper guide pins on this generation of Volvo is around 20-22 ft-lbs (28 Nm). The larger caliper bracket bolts require a much higher torque. Always consult a reliable service manual for your specific vehicle's specifications before starting a job.
