Zimmermann 400.3614.52 Coat Z Cross-Drilled Vented Brake Disc

The Zimmermann 400.3614.52 is a Coat Z Cross-Drilled Vented Brake Disc engineered to deliver precise, reliable stopping power. As an OE-quality replacement rotor from Otto Zimmermann — a manufacturer with deep roots supplying original equipment to leading German automakers — this disc combines proven materials and construction with a performance-oriented cross-drilled design.

Key Features:

• Coat Z Anti-Corrosion Finish: A specially applied coating protects the rotor's non-friction surfaces from rust and corrosion, maintaining a clean, factory-fresh appearance throughout its service life
• Cross-Drilled Braking Surface: Strategically placed drill holes promote continuous expulsion of heat, brake dust, and water vapor for improved wet and dry braking performance
• Vented Construction: Internal vane design maximizes airflow through the rotor core for sustained thermal management under demanding braking conditions
• High-Quality Cast Iron: Manufactured from premium gray cast iron for consistent friction characteristics, long service life, and dimensional stability
• OE-Level Precision: Machined to strict tolerances ensuring proper fitment, minimal runout, and vibration-free braking
• ABE Certified: Includes general ABE certification or ECE documentation, confirming compliance with European automotive safety standards
• Single Disc: This listing is for one (1) brake disc; purchase two for a complete axle replacement

OEM Cross-Reference: 463.421.03.12 (also referenced as 463-421-03-12 / 4634210312). Zimmermann part number also appears as 400-3614-52 / 400361452.

This rotor is sold individually. For optimal braking performance and even wear, it is recommended to replace brake discs in axle pairs and to install new brake pads at the same time.
