Bosch QuietCast Premium Rear Disc Brake Rotor 282mm (Single) – factory-balanced, aluminum/zinc coated

The BOSCH QuietCast Premium Rear Disc Brake Rotor 26011451 is a 282mm, factory-balanced replacement rotor engineered for smooth, quiet braking and long corrosion-resistant service life.

This single rear rotor fits select Acura ILX and TSX models and certain Honda Accord applications, and it’s designed to match OEM fit, form, and function. Bosch QuietCast rotors use precision balancing, an OEM-style vane layout, and a protective aluminum/zinc coating to manage heat, minimize vibration, and resist rust. Built-in features such as an engraved discard thickness and an ABS tone ring on applicable applications make installation and maintenance straightforward for DIYers and professional technicians alike.

How does this rotor improve braking smoothness and reduce pedal pulsation?

The rotor is factory mill precision balanced so weight is distributed evenly around the disc. That precise balancing reduces runout and pedal pulsation under braking, which delivers a noticeably smoother and steadier stop feel without introducing vibration into the system.

• Precision-milled surface to reduce lateral runout.
• Balanced at the factory to eliminate pedal pulsation.
• OEM-style vane configuration for steady cooling and consistent contact.

What keeps this rotor resistant to rust and looking good behind open wheels?

Bosch applies an aluminum/zinc protective coating to the rotor casting to create a barrier against moisture and road salts that cause corrosion. The coating preserves the rotor’s appearance over time, reducing the need for frequent cleaning while helping maintain safe braking performance in wet climates.

• Durable aluminum/zinc coating to slow rust formation.
• Clean finish that complements modern alloy wheels.
• Longer service life before surface degradation appears.

Will this rotor work with ABS and how do I know when to replace it?

On applications that require wheel-speed sensing, Bosch includes an OEM-style ABS tone ring to ensure reliable communication with your vehicle’s anti-lock and traction systems. In addition, every rotor is engraved with a discard thickness marking so you can quickly determine when the rotor has worn to service limit without guessing.

• ABS tone ring present where required for trouble-free operation.
• Engraved discard thickness simplifies inspection and replacement timing.
• Bosch branding on the part confirms authenticity and traceability.

How does the design manage heat and extend rotor life under daily driving?

The QuietCast rotor uses an OEM-style vane pattern that channels airflow efficiently to dissipate heat generated during repeated stops. Better heat management reduces thermal distortion and helps the rotor retain flatness, which lowers the chance of warping and extends useful life under normal driving conditions.

• Vane configuration directs cooling airflow for faster heat rejection.
• Reduced vibration from even heat distribution protects pads and calipers.
• Robust casting and finish help the rotor withstand daily driving stresses.

Who this is for: The BOSCH QuietCast Premium Rear Disc Brake Rotor 26011451 is intended for owners of compatible Acura ILX, TSX, and Honda Accord models seeking an OEM-quality replacement that balances quiet operation, corrosion resistance, and long service life. It suits DIY mechanics who want clear wear indicators and professionals installing reliable rotors for everyday street use. Choose this rotor if you prioritize smooth pedal feel, dependable ABS compatibility, and a corrosion-resistant finish behind open wheels.
