1. Detroit Axle Rear Brake Kit with 10.98" Rotors and Ceramic Pads
| Orientation | Rear |
|---|---|
| Compatible with Vehicle Type | Car |
| Rotor Diameter | 10.98 inch (279mm) |
This Detroit Axle rear brake kit supplies everything needed for a rear brake service: two 10.98 inch vented rotors, two ceramic brake pads with hardware, a can of brake cleaner and a bottle of DOT3 brake fluid. The vented, zinc-coated rotors are machined with locating holes for direct fit and are described as heat-resistant to help cooling and resist corrosion in salted climates. Ceramic pads typically run quieter and produce less dust than semi-metallic pads, and the included hardware and consumables make the kit convenient for a DIY or shop install. Reported fitment and fit accuracy match factory mounting without modification and customers note straightforward installation. Limitations are that this is an aftermarket replacement rather than factory-brand parts, and while the coating helps with corrosion it will wear over time in aggressive environments. If you expect heavy-duty performance driving or very frequent towing, a performance rotor or higher-end pad compound may be a better match.
Best for: Reliability-focused DIYers or owners who prioritize a complete, ready-to-install rear brake service kit that simplifies maintenance and restores dependable stopping performance.
Less Ideal for: Drivers seeking track-oriented braking or heavy towing duty who need high-temperature performance compounds and specialty rotors should consider performance-grade options instead.
- Complete kit includes rotors, ceramic pads, hardware, brake cleaner, and DOT3 fluid for a single rear brake job
- Vented, zinc-plated rotors offer improved cooling and initial corrosion resistance
- Machined locating holes for direct-fit installation that matches factory mounting points
- Ceramic pads are low-noise and produce less dust than many semi-metallic alternatives
- Aftermarket part rather than factory-brand so long-term durability can vary compared with premium OEM replacements
- Coating reduces corrosion but can wear in very harsh road-salt conditions over time
Verdict A well-rounded, reliability-minded rear brake kit for Scion xB owners that bundles rotors, pads, and consumables for an easy brake service at good value.

Choosing the Right Scion xB Brake Rotors: Key Factors to Consider
Material and Casting Quality
Rotor material determines heat capacity, wear rate, and susceptibility to cracking. Most rotors use cast iron because it offers good thermal mass and wear characteristics, but manufacturing quality varies. Look for rotors with consistent metallurgical specs, controlled porosity, and balanced casting to reduce the risk of warping.
Higher casting quality also affects runout and vibration. Better castings are machined or balanced to tighter tolerances, which translates to steadier pedal feel and fewer noise issues. Material quality also influences how the surface accepts pads and resists glazing.
Dimensional Accuracy and Runout
Correct dimensions and low runout are essential for smooth braking. Dimensional accuracy includes diameter, thickness, center bore, and bolt pattern. If any of these are off, fitment problems or rotor wobble can result. Runout measures how much the rotor deviates as it spins and is a primary cause of pedal pulsation.
Buyers should favor rotors with documented manufacturing tolerances and minimal lateral runout. If a rotor arrives outside tolerance, it may require resurfacing or replacement to prevent vibration and uneven pad wear.
Surface Finish and Machining
The rotor face finish affects initial bedding-in, pad contact, and noise. A properly machined and chamfered edge promotes even pad transfer and reduces the chance of squeal. Some rotors come pre-machined to spec; others may need light machining before installation.
A good surface finish also helps with consistent friction levels across the pad contact area. When surface quality is poor, you can see uneven pad deposits that accelerate wear or create hotspots under braking.
Coatings and Corrosion Protection
Coatings protect the hat and non-friction areas from rust, which helps maintain fitment and ease of servicing. Corrosion on mounting surfaces can lead to misalignment or difficulty removing hardware. Zinc or ceramic-style coatings are common choices and can extend the service life of the rotor in wet or salted conditions.
While the friction faces are typically left bare to accept brake pads, quality coatings on other surfaces reduce the chance of seized fasteners and make later servicing simpler.
Design Features: Slotted, Drilled, or Plain
Rotor design affects heat management, pad cleaning, and noise. Plain rotors are simple and generally quieter, with predictable wear for everyday driving. Slotted rotors help sweep gases and pads across the surface for better bite and consistency. Drilled rotors can aid cooling but may be more prone to crack initiation under heavy thermal cycling.
Consider your driving style and conditions. For routine commuting, plain or lightly slotted surfaces often provide the best balance of longevity and quiet operation. For more aggressive stop-and-go or spirited driving, slots or a combination design can help maintain consistent performance.
Serviceability and Resurfacing Options
Think about whether the rotor can be resurfaced when it approaches service limits. Some rotors have minimum thickness margins that allow one or more resurface cycles, while thin or performance-style rotors may not. Resurfacing can correct minor runout and extend life, but removing too much material changes thermal mass and fitment clearances.
Inspect minimum thickness stamped on the rotor and consider whether you plan to replace or resurface in future maintenance. Also factor in ease of removal, bolt access, and whether hub corrosion will complicate service.
FAQ
How do I know when my Scion xB rotors need replacing?
Common signs include a pulsing brake pedal, audible squeal or grinding, visible scoring on the rotor face, and reduced stopping performance. Measure rotor thickness against the vehicles minimum specification or consult a service manual to confirm. If you see deep grooves, severe rust, or exceed the minimum thickness, replacement is usually safer than resurfacing.
Can I resurface rotors instead of replacing them?
Resurfacing can fix minor runout and remove light scoring, but it reduces rotor thickness and therefore heat capacity. It is often acceptable if the rotor is above the minimum thickness and has no cracks. For rotors near the minimum or with structural damage, replacement is the more reliable option.
What is the difference between slotted and drilled rotors for daily driving?
Slotted rotors provide a surface that helps sweep pad material and gases away from the contact area, improving bite consistency. Drilled rotors can improve heat dissipation but may be more vulnerable to cracking under heavy, repeated thermal stress. For routine daily driving, slotted or plain rotors usually offer a better balance of durability and noise control.
How should I measure rotor thickness correctly?
Use a micrometer or caliper to measure at several points on the friction surface, avoiding grooves and edges. Compare the measured thickness to the vehicles minimum specification stamped on the rotor or listed in the service manual. Take multiple readings and use the lowest consistent value to determine serviceability.
Do rotor coatings affect braking performance?
Coatings on the rotor hat and non-friction areas mainly prevent corrosion and do not impact braking friction. The braking surface is usually left uncoated to ensure proper pad contact. Corrosion protection does matter for long-term fitment and ease of service, but it will not change how the rotor interacts with brake pads under load.
Are aftermarket rotors compatible with my Scion xB?
Aftermarket rotors can be compatible if they match the vehicles bolt pattern, center bore, thickness, and mounting features. Always verify documented fitment for the Scion xB and check dimensional specs before purchase. Avoid options that require modification to mounting hardware or hub components.
