Key Features

• Vented disc brake rotor for heat management during braking
• Full cast cast iron construction
• Smooth, directional braking surface
• Conventional rotor design for direct replacement use
• 348 mm outside diameter with 67 mm center hole diameter
• Fits front right applications across multiple BMW model lines

Detailed Description

The Wagner Brake BD181435E is engineered as a conventional vented rotor with a full cast design and cast iron material for dependable braking surface integrity. Its directional, smooth finish supports even pad contact, while the 34.400 mm discard thickness and 36.000 mm nominal thickness provide the dimensional reference needed for service planning. This rotor is a strong match for BMW 230i, 330i, 530i, 540i, 740i, X3, X5, X6, X7, and Z4 front right brake service, along with the 2021 Porsche Cayenne front right application. The BD181435E part number should be verified against the vehicle’s brake package before installation.

What It Helps Address

• Rotor wear that reduces braking consistency
• Surface scoring that affects pad contact
• Heat buildup in vented brake systems
• Brake pulsation caused by worn rotor surfaces
• Service replacement needs on front right brake assemblies

Installation Notes and Tips

Confirm rotor diameter, center hole diameter, and thickness before installation. Match the rotor to the vehicle’s front right brake configuration and inspect pads, caliper condition, and hub surface during service. Because this rotor uses a directional braking surface, install it in the correct orientation for the application.
