Bendix Premium PRT6045 Rear Brake Rotor for BMW 135i 2013-2011 - Quiet

In this review the Bendix Premium PRT6045 rear brake rotor is evaluated for drivers who need a direct OE replacement for a BMW 135i 2011-2013. The bottom line: it delivers predictable stopping power and a quieter ride compared with worn or resurfaced rotors, making it a straightforward choice for owners seeking reliable braking without complications. The review focuses on fit, heat management, noise performance and ease of installation based on product design and customer feedback.

Key Features

• OE Replacement: Designed and engineered to OE specifications so the rotor matches original fit, form, and function for a direct swap.
• Superior Performance: The rotor provides consistent stopping power under typical and demanding driving conditions for confident braking.
• Heat Dissipation: Advanced casting and rotor design help disperse heat efficiently, reducing the risk of brake fade during repeated stops.
• Noise Reduction: Dynamically balanced castings and attention to finish minimize vibration and squeal for a quieter braking experience.
• Durable Construction: Made from high-grade cast iron to withstand daily heat-up and cool-down cycles for long service life.

Who It's For

This rotor is aimed at BMW 135i owners from model years 2011 through 2013 who want a like-for-like replacement that restores original braking feel and quiet operation. It also suits DIY mechanics and independent shops that prefer to replace worn rotors rather than turning them, since customers note good value compared with machining.

Those who need cross-vehicle compatibility beyond the stated fitment should verify fitment before buying, and high performance drivers interested in slotted or drilled racing rotors should look elsewhere for specialty competition designs.

Pros & Cons

Pros

• Good OEM-style fit and function, reducing installation hassles and alignment concerns.
• Quiet braking with low reported noise levels thanks to balanced castings and finish.
• Cost effective compared with rotor turning, delivering solid value for routine replacement.
• Stable performance under heat thanks to the rotor's heat dissipation design.

Cons

• Customers have noted occasional vibration level concerns on some applications, so balancing and hub surfaces should be checked during installation.
• Not a performance drilled or slotted rotor, so it is not targeted at track use or extreme braking applications.
