DuraGo BR902046-01 Front Brake Rotor
The DuraGo BR902046-01 is a front disc brake rotor built for BMW applications that call for a 1-piece, full cast replacement. It combines cast iron construction with a rust-resistant coating on the hat and edge to help maintain appearance and protection in everyday driving conditions.
With a vented, non-directional brake surface and a titanium gray finish, this rotor is a practical choice for BMW 230i, 330i, X3, X4, Z4, and related front brake applications where fit, form, and function matter.
Key Features
- Cast iron, full cast construction for front disc brake service
- Vented rotor design for front axle braking applications
- Rust-resistant coating on the hat and edge
- Titanium gray finish for a cleaner look behind open wheel designs
- Non-directional brake surface for straightforward service replacement
- ISO-certified manufacturing for consistent fit and function
- Part number BR902046-01 for ordering and cross-reference use
Detailed Product Overview
DuraGo engineered the BR902046-01 using its experience in brake components and OE-style replacement standards. This rotor measures 330 mm outside diameter, 24 mm nominal thickness, and 22.4 mm discard thickness, with a 67 mm center hole diameter and 112 mm bolt circle diameter. It uses a 5-bolt mounting pattern and a conventional, full cast rotor construction.
This rotor is a direct-fit front brake rotor for select BMW models, including BMW 230i, BMW 330i, BMW 430i, BMW X3, BMW X4, and BMW Z4 applications listed below. If you are searching for a front brake rotor for BMW 330i xDrive, a front rotor for BMW X3, or a replacement rotor for BMW Z4 front brakes, BR902046-01 is built for those fitments.
This part cross-references Monroe Shocks & Struts (e.g., 34106880072, 34116860907) for the same application.
What This Rotor Helps Address
- Front brake pulsation caused by worn rotor surfaces
- Brake noise related to uneven rotor wear
- Corrosion on exposed rotor hat and edge areas
- Reduced braking consistency from rotor thickness loss
- Replacement needs for OE-style front brake service on select BMW models
