Wagner Brake BD180854E Front Rotor

The Wagner Brake BD180854E is a front disc brake rotor built for Audi applications that call for a 345 mm vented rotor. It uses cast iron construction with a rust-resistant coating to help maintain a clean braking surface and simplify installation.

Key Features

• Cast iron, full cast rotor construction
• Vented design for front brake applications
• Rust-resistant coating on the non-braking surface
• Smooth, directional brake surface
• 13.580 in. outside diameter and 2.051 in. overall height
• 5-lug rotor design
• Part number BD180854E

Detailed Description

Wagner Brake BD180854E is a premium front disc brake rotor engineered for consistent braking performance and corrosion resistance. The cast iron, full cast design provides the mass and stability expected in a front rotor, while the vented construction helps manage heat during repeated stops. The rust-resistant coating supports easier installation and helps protect non-braking surfaces from corrosion. This rotor is a direct fit for select Audi Q5, S5, SQ5, S4, A6, A6 Quattro, and A7 Quattro front brake applications that use a 345 mm diameter rotor. This part cross-references OE numbers 4G0615301AE and 4G0615301AF for the same application. BD180854E is a practical replacement choice when servicing front brake systems on Audi Q5 and Audi S5 models with the specified rotor size.

Installation Notes and Tips

Confirm the vehicle uses a 345 mm front rotor before ordering. Verify rotor diameter, lug count, and front axle application against the existing part and brake system specifications. Clean the hub mounting surface before installation and inspect pads, calipers, and hardware for wear that could affect rotor performance. For best results, pair this rotor with Wagner brake pads.
