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

Bosch QuietCast Premium Rear Disc Brake Rotor (26011446) is a single 333.5mm replacement rotor engineered to restore quiet, consistent braking for compatible Acura and Honda rear axles.

This QuietCast rotor from Bosch is a direct-fit replacement designed for rear-wheel service on specific Acura and Honda models. It combines factory-level balance, an OEM-type vane layout for heat management, and a protective aluminum/zinc finish to resist corrosion and keep braking performance stable over time. The part is sold individually so you can replace one side or match a paired service plan.

Will this rotor fit my vehicle?

Check vehicle compatibility first: Bosch part 26011446 fits certain Acura and Honda models produced in the years listed by the manufacturer. Fitment includes rear rotors and the 333.5mm diameter is the manufacturing specification. Always confirm with your VIN or by comparing the rotor diameter and bolt pattern to the worn rotor.

• Compatible models: Acura MDX (2007–2013), Acura ZDX (2010–2013)
• Compatible models: Honda Odyssey (2011–2015), Honda Pilot (2009–2015)
• Rotor diameter: 333.5 mm; rear axle application
• Sold as a single replacement rotor (not a pair)

How does this rotor help reduce noise and vibration?

Bosch QuietCast rotors are precision balanced at the factory so weight is dispersed evenly around the disc, minimizing pedal pulsation and unwanted vibration. The vane design mirrors OEM geometry to improve airflow and heat evacuation, which reduces thermal-related noise and maintains smooth braking feel. These features work together to keep braking quiet under normal driving conditions.

• Factory precision balancing to prevent pedal pulsation
• OEM-style vane configuration for better heat dissipation
• Reduced vibration for quieter operation under braking

What corrosion protection and service indicators are included?

The rotor arrives with an aluminum/zinc protective coating to slow surface rust, keeping the visible braking surfaces clean and extending serviceable life—especially useful with open-style wheels. Where required, Bosch includes an OEM-style ABS tone ring to maintain Antilock and traction-control sensor accuracy. Bosch also engraves discard thickness directly on the rotor so you can tell when it has reached its safe service limit.

• Aluminum/zinc coating for rust and corrosion resistance
• OEM-style ABS tone ring included on applicable applications
• Engraved discard thickness marking for clear service guidance

What should I know before installing this rotor?

Installation best practices help achieve expected performance: clean mating surfaces, torque hub and caliper hardware to manufacturer specs, and inspect pads and hardware for uneven wear or damage. Because this rotor is sold individually, you may want to replace the opposite-side rotor or brake pads at the same time to preserve balanced braking. If your vehicle uses an ABS tone ring, verify sensor alignment and functionality during installation.

• Clean hub mating surface and properly torque fasteners
• Inspect brake pads and replace in pairs when needed
• Verify ABS tone ring and sensor clearance where applicable

Who is this rotor for? This Bosch QuietCast 26011446 rear rotor is intended for owners and technicians replacing rear braking components on the listed Acura and Honda models who want a direct-fit, OEM-style rotor with anti-corrosion coating, on-part service markings, and balanced construction. It's a practical choice for maintenance shops and DIYers seeking a factory-quality replacement part that preserves ABS and traction control function while helping reduce noise and extend service life.
