DuraGo BR901810 Disc Brake Rotor - Front

DuraGo BR901810 Front Brake Rotor

The DuraGo BR901810 is a front disc brake rotor built for direct-fit service on select Mazda applications. Made from cast iron with a full cast construction, it uses a vented design and a non-directional brake surface to support consistent braking performance and straightforward resurfacing or replacement decisions.

Compatible with 2019-2026 Mazda 3 front, 2019 Mazda 3 Sport front, 2021-2025 Mazda 3 Sport front, and 2020-2025 Mazda CX-30 front, this rotor is sized for the listed applications and built to meet fit, form, and function requirements. The BR901810 is also cross-referenced to Monroe Shocks & Struts 172286 and 182286 for the same application.

What This Rotor Helps Address

• Brake pulsation caused by rotor wear or thickness variation
• Reduced braking smoothness from scored or uneven rotor surfaces
• Rotor replacement needs after reaching discard thickness
• Front brake service on Mazda 3, Mazda 3 Sport, and Mazda CX-30 models
• Noise or vibration associated with worn front brake components

Installation Notes and Tips

Verify rotor dimensions, hub fit, and vehicle application before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake pulsation. Inspect pads, calipers, and hardware condition during service, and confirm the rotor meets the vehicle’s minimum thickness specification after installation. Follow the vehicle manufacturer’s brake service procedures and torque specifications.
