Bosch QuietCast Rear Disc Brake Rotor 333.5mm (Single) — Premium, Corrosion-Resistant

BOSCH 26011446 QuietCast Premium Rear Disc Brake Rotor is a direct-fit, factory-quality 333.5mm replacement rotor engineered to restore smooth, quiet braking for compatible Acura and Honda models.

This QuietCast rotor is built to Bosch standards for fit, balance and surface finish. It replaces the rear rotor on specific Acura MDX and ZDX years and Honda Odyssey and Pilot years, delivering the parts-level details technicians expect: OEM-style vane geometry for cooling, a precision-balanced surface to reduce pedal pulsation, and a protective aluminum/zinc coating to resist corrosion. The single-rotor SKU lets you replace a worn unit or keep a spare on hand for scheduled maintenance.

What makes this rotor a "premium" replacement?

The QuietCast line focuses on NVH (noise, vibration, harshness) control and longevity. Bosch machines each rotor to exacting balance tolerances and uses vane designs that move heat away from the braking surface more efficiently, which reduces warping and vibration over time. A visible Bosch brand mark and engraved discard thickness also help you verify authenticity and serviceability.

• Factory mill precision balance to minimize pedal pulsation
• OEM-style vane configuration for improved cooling
• Engraved discard thickness for easy replacement assessment
• On-the-part Bosch branding to confirm genuine product

How does the aluminum/zinc coating help my vehicle?

The protective coating covers the rotor hat and exposed surfaces to slow rust formation in humid or salty environments, keeping open-wheel caliper assemblies looking cleaner and operating longer between service intervals. It doesn’t change braking friction but protects the rotor's structural surfaces from corrosion that can lead to premature wear.

• Corrosion-resistant finish extends rotor life
• Maintains a cleaner appearance behind open-style wheels
• Helps prevent seizing and surface pitting

Will this rotor work with my ABS and traction control systems?

When your vehicle requires an ABS tone ring, Bosch supplies the rotor with an OEM-style tone ring on compatible applications to ensure reliable wheel-speed sensor readings. This design retains factory system operation so braking electronics continue to perform as intended without additional modifications.

• Includes ABS tone ring where required by application
• Maintains correct sensor spacing and signals for ABS/traction control
• Direct-fit replacement aligns with factory hardware and sensors

How can I tell when the rotor needs replacing?

Each QuietCast rotor has an engraved discard thickness marking on the braking surface edge. Measure thickness with a micrometer or caliper and compare to the stamped discard number; when the rotor reaches that dimension, replacement is recommended to maintain braking performance and safety. Also watch for deep scoring, excessive runout, or cracking.

• Engraved discard thickness visible on the rotor
• Replace if measurements meet or drop below stamped limit
• Inspect for grooves, warpage, or heat-related damage

Who is this rotor for? Bosch 26011446 QuietCast Premium Rear Disc Brake Rotor is intended for owners and technicians servicing compatible Acura MDX (2007–2013), Acura ZDX (2010–2013), Honda Odyssey (2011–2015) and Honda Pilot (2009–2015) models needing a reliable, OEM-style rear rotor. Choose this part if you want a direct-fit replacement that emphasizes balanced stopping, corrosion resistance, and continued compatibility with ABS/traction-control electronics. It’s a practical choice for everyday drivers, fleet maintenance, and anyone seeking a trusted aftermarket rotor backed by Bosch engineering.
