  • Rear brake pulsation caused by rotor wear or thickness variation
  • Reduced braking consistency from a worn or heat-cycled rotor
  • Noise or vibration linked to an uneven braking surface
  • Service replacement needs on BMW rear left brake systems
  • Rotor replacement when the disc reaches discard thickness

Installation notes and quality assurance

Verify rotor dimensions, bolt pattern, center bore, and rear-left position before installation. This rotor is specified as a 1-piece, full cast replacement and is not drilled or slotted. Fitment notes exclude vehicles with painted calipers on certain model years and exclude blue calipers on earlier applications, so confirm brake package details before ordering.

DuraGo manufactures brake drums and rotors through ISO-certified factories and focuses on fit, form, and function for aftermarket brake service. The BR902050 reflects that cataloged OE-style approach for BMW rear brake maintenance.

Part number BR902050 is a direct reference for BMW rear left disc brake rotor replacement across the listed 2017-2026 applications.
