A Guide to Replacing Disc Brake Rotors on the 2008-2014 Scion xD
Everything you need to know about choosing the right aftermarket brake rotors for your Scion xD.
- The most common sign of rotor failure on a Scion xD is a vibration or shudder when braking, usually caused by warped rotors.
- Always replace rotors in pairs and install new brake pads at the same time for safety and performance.
- For daily driving, quality aftermarket brands like Advics (OEM supplier), Centric, or Raybestos offer the best balance of performance and value.
- A safety recall (09V338000) affects the brake booster system on 2008-2009 models in cold climates; this is not a rotor issue but impacts braking feel.
Is it Time to Replace Your Scion xD's Rotors?
The most common sign that your Scion xD's brake rotors are failing is a vibration or pulsation felt in the steering wheel and brake pedal when you apply the brakes. This is often described as a shaking or shuddering and is typically caused by the rotors becoming warped or unevenly worn. 🎬 Watch: See a demonstration of warped rotor symptoms and vibrations. Other symptoms include grinding noises, which can happen when the brake pads are completely worn down causing metal-on-metal contact, and visible grooves or scoring on the rotor's surface.
Known Issues: Safety Recall on 2008-2009 Models
There is a safety recall (NHTSA Campaign ID: 09V338000) for 2008-2009 Scion xD models related to the braking system. In extremely cold temperatures, moisture could freeze in a vacuum port, leading to a gradual loss of power brake assist and increasing the effort needed to stop the car. This is not a defect with the rotors themselves, but it does affect overall braking performance. A dealer can install a redesigned part to correct the issue at no charge.
Choosing the Right Aftermarket Rotors
When shopping for new rotors for your Scion xD, you'll find a wide range of quality and price. For a daily driven vehicle, you don't necessarily need expensive performance parts. However, choosing the cheapest option can sometimes lead to premature warping and noise. Aftermarket brands can be grouped into tiers based on quality and reputation.
OEM-Quality and Premium Aftermarket (Best)
- Advics: As an Original Equipment Manufacturer (OEM) for Toyota, Advics rotors are designed to the same specifications as the parts your Scion xD came with from the factory. They are a top choice for OE-level fit and performance.
- Brembo: A well-respected name in braking, Brembo's OE-replacement rotors are known for high-quality casting and manufacturing, offering excellent performance for daily driving.
- ACDelco: Often considered a reliable brand, their coated rotors offer good corrosion resistance. Some sources suggest their brake products can be reboxed from other quality manufacturers like Raybestos.
Reputable Aftermarket (Better)
- Centric / StopTech: Centric offers several lines, with their premium coated rotors (often black e-coated) providing good corrosion protection and performance for the price. They are a popular choice for a balance of quality and value.
- Raybestos: This brand is a long-standing name in the aftermarket. Their R-Line and Element3 rotors are considered a solid choice for daily drivers, often praised for being a good value.
- Wagner: Known for brake pads, Wagner also offers rotors that are generally well-regarded for daily use, with coated options available to prevent rust on the hat and vanes.
- Bosch: Bosch QuietCast rotors are another solid option that balances quality and affordability for normal commuting.
Economy & Performance Tiers (Good)
- Powerstop: Often sold in kits with pads, Powerstop offers drilled & slotted rotors for those wanting a performance look. For a daily driver, their plain-face or coated OE-replacement rotors are a cost-effective option.
- Dynamic Friction (DFC): This brand offers coated rotors that users find to be a decent value, with rust-proofing that holds up reasonably well.
- Bendix: A brand with a long history, Bendix provides reliable, standard replacement rotors suitable for everyday driving.
- Beck Arnley: This brand often sources parts from various manufacturers, sometimes including OE suppliers. Their rotors are generally considered a reliable aftermarket option.
- Pronto: Often a private label brand for auto parts stores, Pronto rotors are an economy choice that meets basic requirements for fit and function.
Should You Get Drilled or Slotted Rotors?
For a daily driven Scion xD, standard smooth-faced (plain) rotors are the best choice. Drilled and slotted rotors are designed for racing or heavy-duty use to vent gases and heat during constant, aggressive braking. On a street car, they can increase brake pad wear and may be more prone to cracking over time without providing a noticeable benefit.
How Much Should New Rotors Cost?
The cost will vary based on the brand you choose and labor rates in your area. Replacing rotors is almost always done in pairs per axle (both fronts or both rears) and should always include a new set of brake pads.
| Part | Estimated Cost Range |
|---|---|
| New OEM Front Rotors (Pair) | $120 - $180 |
| New Aftermarket Front Rotors (Pair) | $40 - $285 |
| Shop Labor (Front Axle) | 🎬 See this step-by-step walkthrough for replacing your own pads and rotors.$110 - $225 |
Frequently Asked Questions
Can I replace just one rotor?
No, brake rotors must always be replaced in pairs on the same axle (both front wheels or both rear wheels) to ensure even braking performance and safety.
Do I need to replace my pads when I replace my rotors?
Yes, you should always install new brake pads when you install new rotors. Old pads have worn into the pattern of the old rotors and will not make proper contact with the new, flat rotor surface. This can cause noise, vibration, and reduced stopping power.
🎬 Watch: A helpful mechanic shows a basic front disc brake job.What is the difference between OEM and aftermarket rotors?
OEM (Original Equipment Manufacturer) rotors are made by or for Toyota/Scion to the exact specifications of your car. High-quality aftermarket rotors from brands like Advics (an OEM supplier), Brembo, or Centric can meet or exceed OEM quality, often at a lower price. Cheaper aftermarket rotors may use lower-grade metals that can be more prone to warping and wear out faster.
Can I resurface my old rotors instead of replacing them?
Resurfacing (also called 'turning' or 'machining') shaves a thin layer of metal off the rotor to create a new, flat surface. This is only possible if the rotor is still thick enough to remain above the minimum thickness specification stamped on the rotor hub. With the affordable cost of new aftermarket rotors, replacement is often the more time- and cost-effective option.
