Bosch QuietCast Rear Disc Brake Rotor 282mm (Single) — Direct-Fit, Corrosion-Resistant Coated

BOSCH 26011451 QuietCast Premium rear disc brake rotor (282mm) is a single, precision-balanced replacement rotor engineered to restore smooth, quiet braking on compatible Acura and Honda models.

Designed as a direct-fit replacement for select Acura ILX and TSX models and certain Honda Accord applications, this Bosch QuietCast rotor focuses on reliable stopping performance and long-term durability. The rotor arrives ready to install with factory-level balance and protective coating, helping reduce noise, resist corrosion, and maintain consistent braking feel under everyday driving conditions.

How does this rotor reduce brake noise and pedal pulsation?

The rotor is precision-balanced at the factory to ensure even weight distribution, which minimizes uneven rotation that can cause judder or pedal pulsing. Its engineered vane layout helps dissipate heat and cut down vibration that typically contributes to audible brake noise.

• Factory mill balancing for even rotation
• OEM-style internal vanes for efficient heat flow
• Vibration reduction design to keep stopping quiet

What protection does the rotor have against rust and corrosion?

This rotor carries an aluminum/zinc protective finish applied to exposed surfaces to limit rust formation and keep the part looking clean, especially behind open-style wheels. The coating helps preserve mating surfaces and braking performance over time, so the rotor maintains function and appearance longer than an untreated casting.

• Aluminum/zinc surface layer on exposed faces
• Corrosion resistance for longer service life
• Maintains OEM appearance on modern wheel designs

Will the rotor work with ABS and traction control systems?

On applications that require it, the rotor includes an ABS tone ring molded to factory specifications to ensure reliable wheel-speed signal pickup. That on-part tone ring helps preserve compatibility with your vehicle’s anti-lock and traction control systems without extra adapters or sensors.

• OEM-style ABS tone ring where applicable
• Ensures accurate wheel-speed readings for ABS/TC
• Direct-fit design avoids sensor recalibration in most cases

How can I tell when the rotor needs replacement?

Each QuietCast rotor has an engraved discard thickness marker that shows the minimum safe thickness for service. Check this marking during inspection; once the rotor reaches that engraved line, replacement is necessary to preserve braking performance and safety.

• Engraved discard thickness for clear wear limits
• On-the-part Bosch branding for authenticity verification
• Visual inspection points simplify maintenance checks

Who is this for: The Bosch QuietCast 26011451 rear rotor is aimed at DIY mechanics and professional technicians replacing worn or corroded rear rotors on compatible Acura ILX, TSX, and certain Honda Accord models. It suits drivers who want a direct-fit, long-lasting rotor with built-in noise reduction, OEM-style thermal management, and corrosion protection—especially useful for vehicles with exposed wheel designs or where ABS functionality must be preserved.
