Bosch 50011228 QuietCast Premium Disc Brake Rotor Front

The Bosch 50011228 QuietCast Premium Disc Brake Rotor is a front disc brake rotor engineered to deliver quiet, smooth, and reliable stopping performance. Built on Bosch's decades of original equipment braking expertise, the QuietCast line brings OEM-grade quality to the aftermarket with precision manufacturing and innovative materials.

Key Features:

• Factory Mill Precision Balanced: Each rotor is precision balanced at the factory to evenly distribute weight, ensuring smooth, judder-free stops with no pedal pulsation.
• OEM-Style Vane Configuration: Engineered vane geometry provides more efficient heat dissipation, reduces vibration, and extends overall rotor life for quieter operation.
• Aluminum/Zinc (Alutherm 80) Coating: Bi-metal aluminum and zinc coating protects against rust and corrosion while delivering a clean appearance for today's open-wheel vehicle designs.
• Vehicle-Specific Casting: Utilizes vehicle-specific castings produced via a heat flow casting process, resulting in superior G3000, GG20, GG15, and HC (high carbon) iron grades for strength and durability.
• ABS and Traction Control Ready: OEM-style ABS tone ring (on applicable fitments) ensures trouble-free operation of antilock brake and traction control systems.
• Engraved Discard Thickness: Clearly marked discard thickness engraved on the rotor makes it easy to identify when the rotor has reached the end of its service life.
• Authenticated Bosch Branding: On-the-part Bosch brand name confirms authenticity and guarantees you are receiving a genuine Bosch product.
• Front Rotor Diameter: 295.7mm for precise OEM fitment.

The Bosch QuietCast line is built on the same engineering principles Bosch has applied to OEM braking systems since 1936. Minimum tolerance levels and premium materials work together to prevent brake judder, noise, vibration, and harshness — delivering consistent, safe, long-lasting braking performance mile after mile.
