Bosch 0986UB0671 QuietCast Premium Disc Brake Rotor

The Bosch 0986UB0671 is a QuietCast™ Premium Disc Brake Rotor engineered to deliver consistent, vibration-free braking performance. Manufactured to meet or exceed OEM specifications, this replacement brake disc is built to the same exacting standards Bosch applies to original equipment components found on new vehicles worldwide.

Key Features:

• OEM-matched vane configuration provides efficient heat dissipation and reduces vibration for quieter, smoother operation
• Factory mill precision balancing distributes weight evenly for smooth, judder-free stops and eliminates pedal pulsation
• Aluminum/Zinc corrosion-resistant coating protects against rust and extends rotor service life while maintaining a clean appearance on open-wheel designs
• Engraved discard thickness marking provides a clear, on-part reference to indicate when the rotor has reached the end of its service life
• OEM-style ABS tone ring (where required) ensures trouble-free operation of antilock braking and traction control systems
• High-carbon iron construction for improved thermal conductivity, allowing the disc to run cooler under repeated braking demands
• Sold as a single disc — replace in axle pairs for balanced braking performance

The Bosch QuietCast line represents Bosch's commitment to bringing original equipment quality and innovation to the aftermarket. Always replace brake discs in pairs per axle, and install new brake pads whenever brake discs are replaced.
