Detailed Description

DuraGo BR900346 is a conventional rear brake rotor engineered for vehicles that use a solid, full-cast rotor design. Its cast iron construction, 5 mounting bolt holes, and 114.3 mm bolt circle support proper wheel-end fitment, while the non-directional braking surface simplifies rotor service and replacement. This part number BR900346 is a direct replacement option for rear brake maintenance on 2008-2015 Scion xB, 2009-2013 Toyota Matrix, 2009-2010 Pontiac Vibe, and 2016 Scion iM, plus 2017-2018 Toyota Corolla iM rear applications.

DuraGo has over 45 years of aftermarket manufacturing experience, and its brake drum and rotor program is built through ISO-certified factories focused on fit, form, and function. This makes BR900346 a practical choice when replacing a worn rear disc brake rotor on a Toyota Matrix, Scion xB, or related rear brake application. This part cross-references Gates 31508 for the same application.

What This Rotor Helps Address

  • Brake pulsation caused by rotor wear or thickness variation
  • Reduced rear braking performance from a worn rotor surface
  • Noise from uneven or damaged brake rotor contact areas
  • Service issues related to incorrect rotor dimensions
  • Rear brake maintenance on compatible Toyota, Scion, and Pontiac models

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and rear-position fitment before installation. Inspect brake pads, caliper hardware, and hub surfaces for wear or corrosion so the new rotor seats evenly. Clean the rotor friction surfaces before service and follow the vehicle manufacturer’s brake bedding procedure after installation.
