DuraGo BR902046 Front Brake Rotor
The DuraGo BR902046 is a front disc brake rotor built for BMW applications that call for a 1-piece, full cast replacement rotor. It uses cast iron construction with a vented design and non-directional brake surface for straightforward service and consistent braking contact.
Key Features
- Cast iron, full cast construction for front brake service
- Vented rotor design for BMW front axle applications
- Non-directional brake surface
- Conventional rotor design, not cross drilled or slotted
- Outside diameter: 330 mm (12.99 in.)
- Nominal thickness: 24 mm (0.94 in.); discard thickness: 22.4 mm (0.88 in.)
- 5-bolt mounting pattern with 112 mm bolt circle diameter
- Center hole diameter: 67 mm
Detailed Description
DuraGo BR902046 is engineered as a direct front rotor replacement for select BMW 230i, 230i xDrive, Z4, X4, 330e, 330e xDrive, 330i, 330i xDrive, 430i, 430i xDrive, and X3 models. This rotor follows the fitment requirements for 1-piece design, full cast replacement applications, including listings for vehicles with painted calipers or blue calipers where noted in the fitment data. The part number BR902046 is also cross-referenced to OE-style numbers 34106880072 and 34116860907 for the same application.
Built by ISO-certified factories, DuraGo brake rotors are produced to meet fit, form, and function requirements. The full cast, vented design supports front brake service on BMW platforms that use a 330 mm rotor diameter and a 5-lug, 112 mm bolt circle pattern. If you are replacing a worn front rotor on a BMW 330i, BMW X3, or BMW Z4, BR902046 provides the correct dimensional match for the listed applications.
What This Rotor Helps Address
- Brake pulsation caused by rotor wear or thickness variation
- Reduced braking performance from a worn front rotor
- Rotor scoring, grooves, or heat-related surface damage
- Service replacement for BMW front brake maintenance
- Fitment issues when the vehicle requires a 330 mm, 1-piece full cast rotor
Installation Notes and Tips
Verify rotor diameter, center hole size, bolt pattern, and thickness before installation. This rotor is for front position use only and is listed for vehicles with specific caliper configurations, including exceptions for painted calipers and blue calipers. Confirm the vehicle’s brake package against the fitment notes for your BMW 230i, BMW 330i, BMW X3, or other listed model before ordering. Clean the hub mounting surface and inspect pads and calipers during rotor replacement.
Quality Assurance
DuraGo manufactures brake drums and rotors in ISO-certified factories and builds this rotor to meet requirements for fit, form, and function. The BR902046 reflects DuraGo’s focus on catalog accuracy and application-specific brake replacement parts.
